# Snowplow Guide
This document was moved to [another location](../snowplow.md).
This guide provides an overview of how Snowplow works, and implementation details.
For more information about Product Analytics, see:
- [Product Analytics Guide](https://about.gitlab.com/handbook/product/product-analytics-guide/)
- [Usage Ping Guide](usage_ping.md)

## What is Snowplow
Snowplow is an enterprise-grade marketing and product analytics platform which helps track the way users engage with our website and application.
[Snowplow](https://github.com/snowplow/snowplow) consists of the following loosely-coupled sub-systems:
- **Trackers** fire Snowplow events. Snowplow has 12 trackers, covering web, mobile, desktop, server, and IoT.
- **Collectors** receive Snowplow events from trackers. We have three different event collectors, synchronizing events either to Amazon S3, Apache Kafka, or Amazon Kinesis.
- **Enrich** cleans up the raw Snowplow events, enriches them and puts them into storage. We have an Hadoop-based enrichment process, and a Kinesis-based or Kafka-based process.
- **Storage** is where the Snowplow events live. We store the Snowplow events in a flat file structure on S3, and in the Redshift and PostgreSQL databases.
- **Data modeling** is where event-level data is joined with other data sets and aggregated into smaller data sets, and business logic is applied. This produces a clean set of tables which make it easier to perform analysis on the data. We have data models for Redshift and Looker.
- **Analytics** are performed on the Snowplow events or on the aggregate tables.
![snowplow_flow](../img/snowplow_flow.png)
## Snowplow schema
We have many definitions of Snowplow's schema. We have an active issue to [standardize this schema](https://gitlab.com/gitlab-org/gitlab/-/issues/207930) including the following definitions:
- Frontend and backend taxonomy as listed below
- [Structured event taxonomy](#structured-event-taxonomy)
- [Self describing events](https://github.com/snowplow/snowplow/wiki/Custom-events#self-describing-events)
- [Iglu schema](https://gitlab.com/gitlab-org/iglu/)
- [Snowplow authored events](https://github.com/snowplow/snowplow/wiki/Snowplow-authored-events)
## Enabling Snowplow
Tracking can be enabled at:
- The instance level, which enables tracking on both the frontend and backend layers.
- User level, though user tracking can be disabled on a per-user basis. GitLab tracking respects the [Do Not Track](https://www.eff.org/issues/do-not-track) standard, so any user who has enabled the Do Not Track option in their browser is not tracked at a user level.
We use Snowplow for the majority of our tracking strategy and it is enabled on GitLab.com. On a self-managed instance, Snowplow can be enabled by navigating to:
- **Admin Area > Settings > General** in the UI.
- `admin/application_settings/integrations` in your browser.
The following configuration is required:
| Name | Value |
|---------------|---------------------------|
| Collector | `snowplow.trx.gitlab.net` |
| Site ID | `gitlab` |
| Cookie domain | `.gitlab.com` |
## Snowplow request flow
The following example shows a basic request/response flow between the following components:
- Snowplow JS / Ruby Trackers on GitLab.com
- [GitLab.com Snowplow Collector](https://gitlab.com/gitlab-com/gl-infra/readiness/-/blob/master/library/snowplow/index.md)
- The GitLab S3 Bucket

## Structured event taxonomy
When adding new click events, we should add them in a way that's internally consistent. If we don't, it is very painful to perform analysis across features since each feature captures events differently.
The current method provides several attributes that are sent on each click event. Please try to follow these guidelines when specifying events to capture:
| attribute | type | required | description |
| --------- | ------- | -------- | ----------- |
| category | text | true | The page or backend area of the application. Unless infeasible, please use the Rails page attribute by default in the frontend, and namespace + classname on the backend. |
| action | text | true | The action the user is taking, or aspect that's being instrumented. The first word should always describe the action or aspect: clicks should be `click`, activations should be `activate`, creations should be `create`, etc. Use underscores to describe what was acted on; for example, activating a form field would be `activate_form_input`. An interface action like clicking on a dropdown would be `click_dropdown`, while a behavior like creating a project record from the backend would be `create_project` |
| label | text | false | The specific element, or object that's being acted on. This is either the label of the element (e.g. a tab labeled 'Create from template' may be `create_from_template`) or a unique identifier if no text is available (e.g. closing the Groups dropdown in the top navbar might be `groups_dropdown_close`), or it could be the name or title attribute of a record being created. |
| property | text | false | Any additional property of the element, or object being acted on. |
| value | decimal | false | Describes a numeric value or something directly related to the event. This could be the value of an input (e.g. `10` when clicking `internal` visibility). |
### Web-specific parameters
Snowplow JS adds many [web-specific parameters](https://docs.snowplowanalytics.com/docs/collecting-data/collecting-from-own-applications/snowplow-tracker-protocol/#Web-specific_parameters) to all web events by default.
## Implementing Snowplow JS (Frontend) tracking
GitLab provides `Tracking`, an interface that wraps the [Snowplow JavaScript Tracker](https://github.com/snowplow/snowplow/wiki/javascript-tracker) for tracking custom events. There are a few ways to use tracking, but each generally requires at minimum, a `category` and an `action`. Additional data can be provided that adheres to our [Structured event taxonomy](#structured-event-taxonomy).
| field | type | default value | description |
|:-----------|:-------|:---------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `category` | string | document.body.dataset.page | Page or subsection of a page that events are being captured within. |
| `action` | string | 'generic' | Action the user is taking. Clicks should be `click` and activations should be `activate`, so for example, focusing a form field would be `activate_form_input`, and clicking a button would be `click_button`. |
| `data` | object | {} | Additional data such as `label`, `property`, `value`, and `context` as described in our [Structured event taxonomy](#structured-event-taxonomy). |
### Tracking in HAML (or Vue Templates)
When working within HAML (or Vue templates) we can add `data-track-*` attributes to elements of interest. All elements that have a `data-track-event` attribute automatically have event tracking bound on clicks.
Below is an example of `data-track-*` attributes assigned to a button:
```haml
%button.btn{ data: { track: { event: "click_button", label: "template_preview", property: "my-template" } } }
```
```html
<button class="btn"
data-track-event="click_button"
data-track-label="template_preview"
data-track-property="my-template"
/>
```
Event listeners are bound at the document level to handle click events on or within elements with these data attributes. This allows them to be properly handled on re-rendering and changes to the DOM. Note that because of the way these events are bound, click events should not be stopped from propagating up the DOM tree. If for any reason click events are being stopped from propagating, you need to implement your own listeners and follow the instructions in [Tracking in raw JavaScript](#tracking-in-raw-javascript).
Below is a list of supported `data-track-*` attributes:
| attribute | required | description |
|:----------------------|:---------|:------------|
| `data-track-event` | true | Action the user is taking. Clicks must be prepended with `click` and activations must be prepended with `activate`. For example, focusing a form field would be `activate_form_input` and clicking a button would be `click_button`. |
| `data-track-label` | false | The `label` as described in our [Structured event taxonomy](#structured-event-taxonomy). |
| `data-track-property` | false | The `property` as described in our [Structured event taxonomy](#structured-event-taxonomy). |
| `data-track-value` | false | The `value` as described in our [Structured event taxonomy](#structured-event-taxonomy). If omitted, this is the element's `value` property or an empty string. For checkboxes, the default value is the element's checked attribute or `false` when unchecked. |
| `data-track-context` | false | The `context` as described in our [Structured event taxonomy](#structured-event-taxonomy). |
#### Caveats
When using the GitLab helper method [`nav_link`](https://gitlab.com/gitlab-org/gitlab/-/blob/898b286de322e5df6a38d257b10c94974d580df8/app/helpers/tab_helper.rb#L69) be sure to wrap `html_options` under the `html_options` keyword argument.
Be careful, as this behavior can be confused with the `ActionView` helper method [`link_to`](https://api.rubyonrails.org/v5.2.3/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to) that does not require additional wrapping of `html_options`
`nav_link(controller: ['dashboard/groups', 'explore/groups'], html_options: { data: { track_label: "groups_dropdown", track_event: "click_dropdown" } })`
vs
`link_to assigned_issues_dashboard_path, title: _('Issues'), data: { track_label: 'main_navigation', track_event: 'click_issues_link' }`
### Tracking within Vue components
There's a tracking Vue mixin that can be used in components if more complex tracking is required. To use it, first import the `Tracking` library and request a mixin.
```javascript
import Tracking from '~/tracking';
const trackingMixin = Tracking.mixin({ label: 'right_sidebar' });
```
You can provide default options that are passed along whenever an event is tracked from within your component. For instance, if all events within a component should be tracked with a given `label`, you can provide one at this time. Available defaults are `category`, `label`, `property`, and `value`. If no category is specified, `document.body.dataset.page` is used as the default.
You can then use the mixin normally in your component with the `mixin` Vue declaration. The mixin also provides the ability to specify tracking options in `data` or `computed`. These override any defaults and allow the values to be dynamic from props, or based on state.
```javascript
export default {
mixins: [trackingMixin],
// ...[component implementation]...
data() {
return {
expanded: false,
tracking: {
label: 'left_sidebar'
}
};
},
}
```
The mixin provides a `track` method that can be called within the template, or from component methods. An example of the whole implementation might look like the following.
```javascript
export default {
mixins: [Tracking.mixin({ label: 'right_sidebar' })],
data() {
return {
expanded: false,
};
},
methods: {
toggle() {
this.expanded = !this.expanded;
this.track('click_toggle', { value: this.expanded })
}
}
};
```
And if needed within the template, you can use the `track` method directly as well.
```html
<template>
<div>
<a class="toggle" @click.prevent="toggle">Toggle</a>
<div v-if="expanded">
<p>Hello world!</p>
<a @click.prevent="track('click_action')">Track an event</a>
</div>
</div>
</template>
```
### Tracking in raw JavaScript
Custom event tracking and instrumentation can be added by directly calling the `Tracking.event` static function. The following example demonstrates tracking a click on a button by calling `Tracking.event` manually.
```javascript
import Tracking from '~/tracking';
const button = document.getElementById('create_from_template_button');
button.addEventListener('click', () => {
Tracking.event('dashboard:projects:index', 'click_button', {
label: 'create_from_template',
property: 'template_preview',
value: 'rails',
});
})
```
### Tests and test helpers
In Jest particularly in Vue tests, you can use the following:
```javascript
import { mockTracking } from 'helpers/tracking_helper';
describe('MyTracking', () => {
let spy;
beforeEach(() => {
spy = mockTracking('_category_', wrapper.element, jest.spyOn);
});
it('tracks an event when clicked on feedback', () => {
wrapper.find('.discover-feedback-icon').trigger('click');
expect(spy).toHaveBeenCalledWith('_category_', 'click_button', {
label: 'security-discover-feedback-cta',
property: '0',
});
});
});
```
In obsolete Karma tests it's used as below:
```javascript
import { mockTracking, triggerEvent } from 'spec/helpers/tracking_helper';
describe('my component', () => {
let trackingSpy;
beforeEach(() => {
trackingSpy = mockTracking('_category_', vm.$el, spyOn);
});
const triggerEvent = () => {
// action which should trigger a event
};
it('tracks an event when toggled', () => {
expect(trackingSpy).not.toHaveBeenCalled();
triggerEvent('a.toggle');
expect(trackingSpy).toHaveBeenCalledWith('_category_', 'click_edit_button', {
label: 'right_sidebar',
property: 'confidentiality',
});
});
});
```
## Implementing Snowplow Ruby (Backend) tracking
GitLab provides `Gitlab::Tracking`, an interface that wraps the [Snowplow Ruby Tracker](https://github.com/snowplow/snowplow/wiki/ruby-tracker) for tracking custom events.
Custom event tracking and instrumentation can be added by directly calling the `GitLab::Tracking.event` class method, which accepts the following arguments:
| argument | type | default value | description |
|:-----------|:-------|:--------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `category` | string | 'application' | Area or aspect of the application. This could be `HealthCheckController` or `Lfs::FileTransformer` for instance. |
| `action` | string | 'generic' | The action being taken, which can be anything from a controller action like `create` to something like an Active Record callback. |
| `data` | object | {} | Additional data such as `label`, `property`, `value`, and `context` as described in [Structured event taxonomy](#structured-event-taxonomy). These are set as empty strings if you don't provide them. |
Tracking can be viewed as either tracking user behavior, or can be used for instrumentation to monitor and visualize performance over time in an area or aspect of code.
For example:
```ruby
class Projects::CreateService < BaseService
def execute
project = Project.create(params)
Gitlab::Tracking.event('Projects::CreateService', 'create_project',
label: project.errors.full_messages.to_sentence,
value: project.valid?
)
end
end
```
### Unit testing
Use the `expect_snowplow_event` helper when testing backend Snowplow events. See [testing best practices](
https://docs.gitlab.com/ee/development/testing_guide/best_practices.html#test-snowplow-events) for details.
### Performance
We use the [AsyncEmitter](https://github.com/snowplow/snowplow/wiki/Ruby-Tracker#52-the-asyncemitter-class) when tracking events, which allows for instrumentation calls to be run in a background thread. This is still an active area of development.
## Developing and testing Snowplow

1. Open the Chrome extension by pressing the Snowplow Inspector icon beside the address bar.
1. Click around on a webpage with Snowplow and you should see JavaScript events firing in the inspector window.
### Snowplow Micro
Snowplow Micro is a very small version of a full Snowplow data collection pipeline: small enough that it can be launched by a test suite. Events can be recorded into Snowplow Micro just as they can a full Snowplow pipeline. Micro then exposes an API that can be queried.
Snowplow Micro is a Docker-based solution for testing frontend and backend events in a local development environment. You need to modify GDK using the instructions below to set this up.
- Read [Introducing Snowplow Micro](https://snowplowanalytics.com/blog/2019/07/17/introducing-snowplow-micro/)
- Look at the [Snowplow Micro repository](https://github.com/snowplow-incubator/snowplow-micro)
- Watch our [installation guide recording](https://www.youtube.com/watch?v=OX46fo_A0Ag)
1. Ensure Docker is installed and running.
1. Install [Snowplow Micro](https://github.com/snowplow-incubator/snowplow-micro) by cloning the settings in [this project](https://gitlab.com/gitlab-org/snowplow-micro-configuration):
1. Navigate to the directory with the cloned project, and start the appropriate Docker
container with the following script:
```shell
./snowplow-micro.sh
```
1. Update your instance's settings to enable Snowplow events and point to the Snowplow Micro collector:
```shell
gdk psql -d gitlabhq_development
update application_settings set snowplow_collector_hostname='localhost:9090', snowplow_enabled=true, snowplow_cookie_domain='.gitlab.com';
```
1. Update `DEFAULT_SNOWPLOW_OPTIONS` in `app/assets/javascripts/tracking.js` to remove `forceSecureTracker: true`:
```diff

# Usage Ping Guide
This document was moved to [another location](../usage_ping.md).
> - Introduced in GitLab Enterprise Edition 8.10.
> - More statistics were added in GitLab Enterprise Edition 8.12.
> - Moved to GitLab Core in 9.1.
> - More statistics were added in GitLab Ultimate 11.2.
This guide describes Usage Ping's purpose and how it's implemented.
For more information about Product Analytics, see:

## What is Usage Ping?
- GitLab sends a weekly payload containing usage data to GitLab Inc. Usage Ping provides high-level data to help our product, support, and sales teams. It does not send any project names, usernames, or any other specific data. The information from the usage ping is not anonymous, it is linked to the hostname of the instance. Sending usage ping is optional, and any instance can disable analytics.
- The usage data is primarily composed of row counts for different tables in the instance’s database. By comparing these counts month over month (or week over week), we can get a rough sense for how an instance is using the different features within the product. In addition to counts, other facts
that help us classify and understand GitLab installations are collected.
- Usage ping is important to GitLab as we use it to calculate our Stage Monthly Active Users (SMAU) which helps us measure the success of our stages and features.
- While usage ping is enabled, GitLab gathers data from the other instances and can show usage statistics of your instance to your users.
### Why should we enable Usage Ping?
- The main purpose of Usage Ping is to build a better GitLab. Data about how GitLab is used is collected to better understand feature/stage adoption and usage, which helps us understand how GitLab is adding value and helps our team better understand the reasons why people use GitLab and with this knowledge we're able to make better product decisions.
- As a benefit of having the usage ping active, GitLab lets you analyze the users’ activities over time of your GitLab installation.
- As a benefit of having the usage ping active, GitLab provides you with The DevOps Report,which gives you an overview of your entire instance’s adoption of Concurrent DevOps from planning to monitoring.
- You get better, more proactive support. (assuming that our TAMs and support organization used the data to deliver more value)
- You get insight and advice into how to get the most value out of your investment in GitLab. Wouldn't you want to know that a number of features or values are not being adopted in your organization?
- You get a report that illustrates how you compare against other similar organizations (anonymized), with specific advice and recommendations on how to improve your DevOps processes.
- Usage Ping is enabled by default. To disable it, see [Disable Usage Ping](#disable-usage-ping).
### Limitations
- Usage Ping does not track frontend events things like page views, link clicks, or user sessions, and only focuses on aggregated backend events.
- Because of these limitations we recommend instrumenting your products with Snowplow for more detailed analytics on GitLab.com and use Usage Ping to track aggregated backend events on self-managed.
## Usage Ping payload
You can view the exact JSON payload sent to GitLab Inc. in the administration panel. To view the payload:
1. Navigate to **Admin Area > Settings > Metrics and profiling**.
1. Expand the **Usage statistics** section.
1. Click the **Preview payload** button.
For an example payload, see [Example Usage Ping payload](#example-usage-ping-payload).
## Disable Usage Ping
To disable Usage Ping in the GitLab UI, go to the **Settings** page of your administration panel and uncheck the **Usage Ping** checkbox.
To disable Usage Ping and prevent it from being configured in the future through the administration panel, Omnibus installs can set the following in [`gitlab.rb`](https://docs.gitlab.com/omnibus/settings/configuration.html#configuration-options):
```ruby
gitlab_rails['usage_ping_enabled'] = false
```
Source installations can set the following in `gitlab.yml`:
```yaml
production: &base
# ...
gitlab:
# ...
usage_ping_enabled: false
```
## Usage Ping request flow
The following example shows a basic request/response flow between a GitLab instance, the Versions Application, the License Application, Salesforce, the GitLab S3 Bucket, the GitLab Snowflake Data Warehouse, and Sisense:
```mermaid
sequenceDiagram
participant GitLab Instance
participant Versions Application
participant Licenses Application
participant Salesforce
participant S3 Bucket
participant Snowflake DW
participant Sisense Dashboards
GitLab Instance->>Versions Application: Send Usage Ping
loop Process usage data
Versions Application->>Versions Application: Parse usage data
Versions Application->>Versions Application: Write to database
Versions Application->>Versions Application: Update license ping time
end
loop Process data for Salesforce
Versions Application-xLicenses Application: Request Zuora subscription id
Licenses Application-xVersions Application: Zuora subscription id
Versions Application-xSalesforce: Request Zuora account id by Zuora subscription id
Salesforce-xVersions Application: Zuora account id
Versions Application-xSalesforce: Usage data for the Zuora account
end
Versions Application->>S3 Bucket: Export Versions database
S3 Bucket->>Snowflake DW: Import data
Snowflake DW->>Snowflake DW: Transform data using dbt
Snowflake DW->>Sisense Dashboards: Data available for querying
Versions Application->>GitLab Instance: DevOps Report (Conversational Development Index)
```
## How Usage Ping works
1. The Usage Ping [cron job](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/workers/gitlab_usage_ping_worker.rb#L30) is set in Sidekiq to run weekly.
1. When the cron job runs, it calls [`Gitlab::UsageData.to_json`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/submit_usage_ping_service.rb#L22).
1. `Gitlab::UsageData.to_json` [cascades down](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb#L22) to ~400+ other counter method calls.
1. The response of all methods calls are [merged together](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb#L14) into a single JSON payload in `Gitlab::UsageData.to_json`.
1. The JSON payload is then [posted to the Versions application]( https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/submit_usage_ping_service.rb#L20)
If a firewall exception is needed, the required URL depends on several things. If
the hostname is `version.gitlab.com`, the protocol is `TCP`, and the port number is `443`,
the required URL is <https://version.gitlab.com/>.
## Implementing Usage Ping
Usage Ping consists of two kinds of data, counters and observations. Counters track how often a certain event
happened over time, such as how many CI pipelines have run. They are monotonic and always trend up.
Observations are facts collected from one or more GitLab instances and can carry arbitrary data. There are no
general guidelines around how to collect those, due to the individual nature of that data.
There are several types of counters which are all found in `usage_data.rb`:
- **Ordinary Batch Counters:** Simple count of a given ActiveRecord_Relation
- **Distinct Batch Counters:** Distinct count of a given ActiveRecord_Relation in a given column
- **Sum Batch Counters:** Sum the values of a given ActiveRecord_Relation in a given column
- **Alternative Counters:** Used for settings and configurations
- **Redis Counters:** Used for in-memory counts.
NOTE:
Only use the provided counter methods. Each counter method contains a built in fail safe to isolate each counter to avoid breaking the entire Usage Ping.
### Why batch counting
For large tables, PostgreSQL can take a long time to count rows due to MVCC [(Multi-version Concurrency Control)](https://en.wikipedia.org/wiki/Multiversion_concurrency_control). Batch counting is a counting method where a single large query is broken into multiple smaller queries. For example, instead of a single query querying 1,000,000 records, with batch counting, you can execute 100 queries of 10,000 records each. Batch counting is useful for avoiding database timeouts as each batch query is significantly shorter than one single long running query.
For GitLab.com, there are extremely large tables with 15 second query timeouts, so we use batch counting to avoid encountering timeouts. Here are the sizes of some GitLab.com tables:
| Table | Row counts in millions |
|------------------------------|------------------------|
| `merge_request_diff_commits` | 2280 |
| `ci_build_trace_sections` | 1764 |
| `merge_request_diff_files` | 1082 |
| `events` | 514 |
We have several batch counting methods available:
- `Ordinary Batch Counters`
- `Distinct Batch Counters`
- `Sum Batch Counters`
- `Estimated Batch Counters`
Batch counting requires indexes on columns to calculate max, min, and range queries. In some cases,
you may need to add a specialized index on the columns involved in a counter.
### Ordinary Batch Counters
Handles `ActiveRecord::StatementInvalid` error
Simple count of a given ActiveRecord_Relation, does a non-distinct batch count, smartly reduces batch_size and handles errors.
Method: `count(relation, column = nil, batch: true, start: nil, finish: nil)`
Arguments:
- `relation` the ActiveRecord_Relation to perform the count
- `column` the column to perform the count on, by default is the primary key
- `batch`: default `true` in order to use batch counting
- `start`: custom start of the batch counting in order to avoid complex min calculations
- `end`: custom end of the batch counting in order to avoid complex min calculations
Examples:
```ruby
count(User.active)
count(::Clusters::Cluster.aws_installed.enabled, :cluster_id)
count(::Clusters::Cluster.aws_installed.enabled, :cluster_id, start: ::Clusters::Cluster.minimum(:id), finish: ::Clusters::Cluster.maximum(:id))
```
### Distinct Batch Counters
Handles `ActiveRecord::StatementInvalid` error
Distinct count of a given ActiveRecord_Relation on given column, a distinct batch count, smartly reduces batch_size and handles errors.
Method: `distinct_count(relation, column = nil, batch: true, batch_size: nil, start: nil, finish: nil)`
Arguments:
- `relation` the ActiveRecord_Relation to perform the count
- `column` the column to perform the distinct count, by default is the primary key
- `batch`: default `true` in order to use batch counting
- `batch_size`: if none set it uses default value 10000 from `Gitlab::Database::BatchCounter`
- `start`: custom start of the batch counting in order to avoid complex min calculations
- `end`: custom end of the batch counting in order to avoid complex min calculations
WARNING:
Counting over non-unique columns can lead to performance issues. Take a look at the [iterating tables in batches](../iterating_tables_in_batches.md) guide for more details.
Examples:
```ruby
distinct_count(::Project, :creator_id)
distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::User.minimum(:id), finish: ::User.maximum(:id))
distinct_count(::Clusters::Applications::CertManager.where(time_period).available.joins(:cluster), 'clusters.user_id')
```
### Sum Batch Counters
Handles `ActiveRecord::StatementInvalid` error
Sum the values of a given ActiveRecord_Relation on given column and handles errors.
Method: `sum(relation, column, batch_size: nil, start: nil, finish: nil)`
Arguments:
- `relation` the ActiveRecord_Relation to perform the operation
- `column` the column to sum on
- `batch_size`: if none set it uses default value 1000 from `Gitlab::Database::BatchCounter`
- `start`: custom start of the batch counting in order to avoid complex min calculations
- `end`: custom end of the batch counting in order to avoid complex min calculations
Examples:
```ruby
sum(JiraImportState.finished, :imported_issues_count)
```
### Grouping & Batch Operations
The `count`, `distinct_count`, and `sum` batch counters can accept an `ActiveRecord::Relation`
object, which groups by a specified column. With a grouped relation, the methods do batch counting,
handle errors, and returns a hash table of key-value pairs.
Examples:
```ruby
count(Namespace.group(:type))
# returns => {nil=>179, "Group"=>54}
distinct_count(Project.group(:visibility_level), :creator_id)
# returns => {0=>1, 10=>1, 20=>11}
sum(Issue.group(:state_id), :weight))
# returns => {1=>3542, 2=>6820}
```
### Estimated Batch Counters
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/48233) in GitLab 13.7.
Estimated batch counter functionality handles `ActiveRecord::StatementInvalid` errors
when used through the provided `estimate_batch_distinct_count` method.
Errors return a value of `-1`.
WARNING:
This functionality estimates a distinct count of a specific ActiveRecord_Relation in a given column,
which uses the [HyperLogLog](http://algo.inria.fr/flajolet/Publications/FlFuGaMe07.pdf) algorithm.
As the HyperLogLog algorithm is probabilistic, the **results always includes error**.
The highest encountered error rate is 4.9%.
When correctly used, the `estimate_batch_distinct_count` method enables efficient counting over
columns that contain non-unique values, which can not be assured by other counters.
Method: [`estimate_batch_distinct_count(relation, column = nil, batch_size: nil, start: nil, finish: nil)`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/utils/usage_data.rb#L63)
The method includes the following arguments:
- `relation`: The ActiveRecord_Relation to perform the count.
- `column`: The column to perform the distinct count. The default is the primary key.
- `batch_size`: The default is 10,000, from `Gitlab::Database::PostgresHll::BatchDistinctCounter::DEFAULT_BATCH_SIZE`.
- `start`: The custom start of the batch count, to avoid complex minimum calculations.
- `finish`: The custom end of the batch count in order to avoid complex maximum calculations.
The method includes the following prerequisites:
1. The supplied `relation` must include the primary key defined as the numeric column.
For example: `id bigint NOT NULL`.
1. The `estimate_batch_distinct_count` can handle a joined relation. To utilize its ability to
count non-unique columns, the joined relation **must NOT** have a one-to-many relationship,
such as `has_many :boards`.
1. Both `start` and `finish` arguments should always represent primary key relationship values,
even if the estimated count refers to another column, for example:
```ruby
estimate_batch_distinct_count(::Note, :author_id, start: ::Note.minimum(:id), finish: ::Note.maximum(:id))
```
Examples:
1. Simple execution of estimated batch counter, with only relation provided, returned value will represent estimated
number of unique values in `id` column (which is the primary key) of `Project` relation:
```ruby
estimate_batch_distinct_count(::Project)
```
1. Execution of estimated batch counter, where provided relation has applied additional filter (`.where(time_period)`), number of unique values is going to be estimated in custom column (`:author_id`), and parameters: `start` and `finish` together apply boundaries that defines range of provided relation that is going to be analyzed
```ruby
estimate_batch_distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::Note.minimum(:id), finish: ::Note.maximum(:id))
```
1. Execution of estimated batch counter with joined relation (`joins(:cluster)`), for a custom column (`'clusters.user_id'`):
```ruby
estimate_batch_distinct_count(::Clusters::Applications::CertManager.where(time_period).available.joins(:cluster), 'clusters.user_id')
```
When instrumenting metric with usage of estimated batch counter please add `_estimated` suffix to its name, for example:
```ruby
"counts": {
"ci_builds_estimated": estimate_batch_distinct_count(Ci::Build),
...
```
### Redis Counters
Handles `::Redis::CommandError` and `Gitlab::UsageDataCounters::BaseCounter::UnknownEvent`
returns -1 when a block is sent or hash with all values -1 when a `counter(Gitlab::UsageDataCounters)` is sent
different behavior due to 2 different implementations of Redis counter
Method: `redis_usage_data(counter, &block)`
Arguments:
- `counter`: a counter from `Gitlab::UsageDataCounters`, that has `fallback_totals` method implemented
- or a `block`: which is evaluated
#### Ordinary Redis Counters
Examples of implementation:
- Using Redis methods [`INCR`](https://redis.io/commands/incr), [`GET`](https://redis.io/commands/get), and [`Gitlab::UsageDataCounters::WikiPageCounter`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/wiki_page_counter.rb)
- Using Redis methods [`HINCRBY`](https://redis.io/commands/hincrby), [`HGETALL`](https://redis.io/commands/hgetall), and [`Gitlab::UsageCounters::PodLogs`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_counters/pod_logs.rb)
##### UsageData API Tracking
<!-- There's nearly identical content in `##### Adding new events`. If you fix errors here, you may need to fix the same errors in the other location. -->
1. Track event using `UsageData` API
Increment event count using ordinary Redis counter, for given event name.
Tracking events using the `UsageData` API requires the `usage_data_api` feature flag to be enabled, which is enabled by default.
API requests are protected by checking for a valid CSRF token.
In order to be able to increment the values the related feature `usage_data_<event_name>` should be enabled.
```plaintext
POST /usage_data/increment_counter
```
| Attribute | Type | Required | Description |
| :-------- | :--- | :------- | :---------- |
| `event` | string | yes | The event name it should be tracked |
Response
- `200` if event was tracked
- `400 Bad request` if event parameter is missing
- `401 Unauthorized` if user is not authenticated
- `403 Forbidden` for invalid CSRF token provided
1. Track events using JavaScript/Vue API helper which calls the API above
Note that `usage_data_api` and `usage_data_#{event_name}` should be enabled in order to be able to track events
```javascript
import api from '~/api';
api.trackRedisCounterEvent('my_already_defined_event_name'),
```
#### Redis HLL Counters
WARNING:
HyperLogLog (HLL) is a probabilistic algorithm and its **results always includes some small error**. According to [Redis documentation](https://redis.io/commands/pfcount), data from
used HLL implementation is "approximated with a standard error of 0.81%".
With `Gitlab::UsageDataCounters::HLLRedisCounter` we have available data structures used to count unique values.
Implemented using Redis methods [PFADD](https://redis.io/commands/pfadd) and [PFCOUNT](https://redis.io/commands/pfcount).
##### Adding new events
1. Define events in [`known_events`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/).
Example event:
```yaml
- name: i_compliance_credential_inventory
category: compliance
redis_slot: compliance
expiry: 42 # 6 weeks
aggregation: weekly
```
Keys:
- `name`: unique event name.
Name format `<prefix>_<redis_slot>_name`.
Use one of the following prefixes for the event's name:
- `g_` for group, as an event which is tracked for group.
- `p_` for project, as an event which is tracked for project.
- `i_` for instance, as an event which is tracked for instance.
- `a_` for events encompassing all `g_`, `p_`, `i_`.
- `o_` for other.
Consider including in the event's name the Redis slot in order to be able to count totals for a specific category.
Example names: `i_compliance_credential_inventory`, `g_analytics_contribution`.
- `category`: event category. Used for getting total counts for events in a category, for easier
access to a group of events.
- `redis_slot`: optional Redis slot; default value: event name. Used if needed to calculate totals
for a group of metrics. Ensure keys are in the same slot. For example:
`i_compliance_credential_inventory` with `redis_slot: 'compliance'` builds Redis key
`i_{compliance}_credential_inventory-2020-34`. If `redis_slot` is not defined the Redis key will
be `{i_compliance_credential_inventory}-2020-34`.
- `expiry`: expiry time in days. Default: 29 days for daily aggregation and 6 weeks for weekly
aggregation.
- `aggregation`: may be set to a `:daily` or `:weekly` key. Defines how counting data is stored in Redis.
Aggregation on a `daily` basis does not pull more fine grained data.
- `feature_flag`: optional. For details, see our [GitLab internal Feature flags](../feature_flags/) documentation.
1. Track event in controller using `RedisTracking` module with `track_redis_hll_event(*controller_actions, name:, feature:, feature_default_enabled: false)`.
Arguments:
- `controller_actions`: controller actions we want to track.
- `name`: event name.
- `feature`: feature name, all metrics we track should be under feature flag.
- `feature_default_enabled`: feature flag is disabled by default, set to `true` for it to be enabled by default.
Example usage:
```ruby
# controller
class ProjectsController < Projects::ApplicationController
include RedisTracking
skip_before_action :authenticate_user!, only: :show
track_redis_hll_event :index, :show, name: 'g_compliance_example_feature_visitors', feature: :compliance_example_feature, feature_default_enabled: true
def index
render html: 'index'
end
def new
render html: 'new'
end
def show
render html: 'show'
end
end
```
1. Track event in API using `increment_unique_values(event_name, values)` helper method.
In order to be able to track the event, Usage Ping must be enabled and the event feature `usage_data_<event_name>` must be enabled.
Arguments:
- `event_name`: event name.
- `values`: values counted, one value or array of values.
Example usage:
```ruby
get ':id/registry/repositories' do
repositories = ContainerRepositoriesFinder.new(
user: current_user, subject: user_group
).execute
increment_unique_values('i_list_repositories', current_user.id)
present paginate(repositories), with: Entities::ContainerRegistry::Repository, tags: params[:tags], tags_count: params[:tags_count]
end
```
1. Track event using `track_usage_event(event_name, values) in services and graphql
Increment unique values count using Redis HLL, for given event name.
Example:
[Track usage event for incident created in service](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/issues/update_service.rb)
[Track usage event for incident created in graphql](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/graphql/mutations/alert_management/update_alert_status.rb)
```ruby
track_usage_event(:incident_management_incident_created, current_user.id)
```
<!-- There's nearly identical content in `##### UsageData API Tracking`. If you find / fix errors here, you may need to fix errors in that section too. -->
1. Track event using `UsageData` API
Increment unique users count using Redis HLL, for given event name.
Tracking events using the `UsageData` API requires the `usage_data_api` feature flag to be enabled, which is enabled by default.
API requests are protected by checking for a valid CSRF token.
In order to increment the values, the related feature `usage_data_<event_name>` should be
set to `default_enabled: true`. For more information, see
[Feature flags in development of GitLab](../feature_flags/index.md).
```plaintext
POST /usage_data/increment_unique_users
```
| Attribute | Type | Required | Description |
| :-------- | :--- | :------- | :---------- |
| `event` | string | yes | The event name it should be tracked |
Response
Return 200 if tracking failed for any reason.
- `200` if event was tracked or any errors
- `400 Bad request` if event parameter is missing
- `401 Unauthorized` if user is not authenticated
- `403 Forbidden` for invalid CSRF token provided
1. Track events using JavaScript/Vue API helper which calls the API above
Example usage for an existing event already defined in [known events](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/):
Usage Data API is behind `usage_data_api` feature flag which, as of GitLab 13.7, is
now set to `default_enabled: true`.
Each event tracked using Usage Data API is behind a feature flag `usage_data_#{event_name}` which should be `default_enabled: true`
```javascript
import api from '~/api';
api.trackRedisHllUserEvent('my_already_defined_event_name'),
```
1. Track event using base module `Gitlab::UsageDataCounters::HLLRedisCounter.track_event(event_name, values:)`.
Arguments:
- `event_name`: event name.
- `values`: One value or array of values we count. For example: user_id, visitor_id, user_ids.
1. Track event on context level using base module `Gitlab::UsageDataCounters::HLLRedisCounter.track_event_in_context(event_name, values:, context:)`.
Arguments:
- `event_name`: event name.
- `values`: values we count. For example: user_id, visitor_id.
- `context`: context value. Allowed values are `default`, `free`, `bronze`, `silver`, `gold`, `starter`, `premium`, `ultimate`
1. Get event data using `Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names:, start_date:, end_date:, context: '')`.
Arguments:
- `event_names`: the list of event names.
- `start_date`: start date of the period for which we want to get event data.
- `end_date`: end date of the period for which we want to get event data.
- `context`: context of the event. Allowed values are `default`, `free`, `bronze`, `silver`, `gold`, `starter`, `premium`, `ultimate`.
1. Testing tracking and getting unique events
Trigger events in rails console by using `track_event` method
```ruby
Gitlab::UsageDataCounters::HLLRedisCounter.track_event('g_compliance_audit_events', values: 1)
Gitlab::UsageDataCounters::HLLRedisCounter.track_event('g_compliance_audit_events', values: [2, 3])
```
Next, get the unique events for the current week.
```ruby
# Get unique events for metric for current_week
Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names: 'g_compliance_audit_events',
start_date: Date.current.beginning_of_week, end_date: Date.current.end_of_week)
```
##### Recommendations
We have the following recommendations for [Adding new events](#adding-new-events):
- Event aggregation: weekly.
- Key expiry time:
- Daily: 29 days.
- Weekly: 42 days.
- When adding new metrics, use a [feature flag](../../operations/feature_flags.md) to control the impact.
- For feature flags triggered by another service, set `default_enabled: false`,
- Events can be triggered using the `UsageData` API, which helps when there are > 10 events per change
##### Enable/Disable Redis HLL tracking
Events are tracked behind [feature flags](../feature_flags/index.md) due to concerns for Redis performance and scalability.
For a full list of events and corresponding feature flags see, [known_events](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/) files.
To enable or disable tracking for specific event within <https://gitlab.com> or <https://about.staging.gitlab.com>, run commands such as the following to
[enable or disable the corresponding feature](../feature_flags/index.md).
```shell
/chatops run feature set <feature_name> true
/chatops run feature set <feature_name> false
```
##### Known events are added automatically in usage data payload
All events added in [`known_events/common.yml`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/common.yml) are automatically added to usage data generation under the `redis_hll_counters` key. This column is stored in [version-app as a JSON](https://gitlab.com/gitlab-services/version-gitlab-com/-/blob/master/db/schema.rb#L209).
For each event we add metrics for the weekly and monthly time frames, and totals for each where applicable:
- `#{event_name}_weekly`: Data for 7 days for daily [aggregation](#adding-new-events) events and data for the last complete week for weekly [aggregation](#adding-new-events) events.
- `#{event_name}_monthly`: Data for 28 days for daily [aggregation](#adding-new-events) events and data for the last 4 complete weeks for weekly [aggregation](#adding-new-events) events.
Redis HLL implementation calculates automatic total metrics, if there are more than one metric for the same category, aggregation and Redis slot.
- `#{category}_total_unique_counts_weekly`: Total unique counts for events in the same category for the last 7 days or the last complete week, if events are in the same Redis slot and we have more than one metric.
- `#{category}_total_unique_counts_monthly`: Total unique counts for events in same category for the last 28 days or the last 4 complete weeks, if events are in the same Redis slot and we have more than one metric.
Example of `redis_hll_counters` data:
```ruby
{:redis_hll_counters=>
{"compliance"=>
{"g_compliance_dashboard_weekly"=>0,
"g_compliance_dashboard_monthly"=>0,
"g_compliance_audit_events_weekly"=>0,
"g_compliance_audit_events_monthly"=>0,
"compliance_total_unique_counts_weekly"=>0,
"compliance_total_unique_counts_monthly"=>0},
"analytics"=>
{"g_analytics_contribution_weekly"=>0,
"g_analytics_contribution_monthly"=>0,
"g_analytics_insights_weekly"=>0,
"g_analytics_insights_monthly"=>0,
"analytics_total_unique_counts_weekly"=>0,
"analytics_total_unique_counts_monthly"=>0},
"ide_edit"=>
{"g_edit_by_web_ide_weekly"=>0,
"g_edit_by_web_ide_monthly"=>0,
"g_edit_by_sfe_weekly"=>0,
"g_edit_by_sfe_monthly"=>0,
"ide_edit_total_unique_counts_weekly"=>0,
"ide_edit_total_unique_counts_monthly"=>0},
"search"=>
{"i_search_total_weekly"=>0, "i_search_total_monthly"=>0, "i_search_advanced_weekly"=>0, "i_search_advanced_monthly"=>0, "i_search_paid_weekly"=>0, "i_search_paid_monthly"=>0, "search_total_unique_counts_weekly"=>0, "search_total_unique_counts_monthly"=>0},
"source_code"=>{"wiki_action_weekly"=>0, "wiki_action_monthly"=>0}
}
```
Example usage:
```ruby
# Redis Counters
redis_usage_data(Gitlab::UsageDataCounters::WikiPageCounter)
redis_usage_data { ::Gitlab::UsageCounters::PodLogs.usage_totals[:total] }
# Define events in common.yml https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/common.yml
# Tracking events
Gitlab::UsageDataCounters::HLLRedisCounter.track_event('expand_vulnerabilities', values: visitor_id)
# Get unique events for metric
redis_usage_data { Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names: 'expand_vulnerabilities', start_date: 28.days.ago, end_date: Date.current) }
```
### Alternative Counters
Handles `StandardError` and fallbacks into -1 this way not all measures fail if we encounter one exception.
Mainly used for settings and configurations.
Method: `alt_usage_data(value = nil, fallback: -1, &block)`
Arguments:
- `value`: a simple static value in which case the value is simply returned.
- or a `block`: which is evaluated
- `fallback: -1`: the common value used for any metrics that are failing.
Example of usage:
```ruby
alt_usage_data { Gitlab::VERSION }
alt_usage_data { Gitlab::CurrentSettings.uuid }
alt_usage_data(999)
```
### Prometheus Queries
In those cases where operational metrics should be part of Usage Ping, a database or Redis query is unlikely
to provide useful data. Instead, Prometheus might be more appropriate, since most GitLab architectural
components publish metrics to it that can be queried back, aggregated, and included as usage data.
NOTE:
Prometheus as a data source for Usage Ping is currently only available for single-node Omnibus installations
that are running the [bundled Prometheus](../../administration/monitoring/prometheus/index.md) instance.
To query Prometheus for metrics, a helper method is available to `yield` a fully configured
`PrometheusClient`, given it is available as per the note above:
```ruby
with_prometheus_client do |client|
response = client.query('<your query>')
...
end
```
Please refer to [the `PrometheusClient` definition](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/prometheus_client.rb)
for how to use its API to query for data.
## Developing and testing Usage Ping
### 1. Naming and placing the metrics
Add the metric in one of the top level keys
- `license`: for license related metrics.
- `settings`: for settings related metrics.
- `counts_weekly`: for counters that have data for the most recent 7 days.
- `counts_monthly`: for counters that have data for the most recent 28 days.
- `counts`: for counters that have data for all time.
### 2. Use your Rails console to manually test counters
```ruby
# count
Gitlab::UsageData.count(User.active)
Gitlab::UsageData.count(::Clusters::Cluster.aws_installed.enabled, :cluster_id)
# count distinct
Gitlab::UsageData.distinct_count(::Project, :creator_id)
Gitlab::UsageData.distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::User.minimum(:id), finish: ::User.maximum(:id))
```
### 3. Generate the SQL query
Your Rails console returns the generated SQL queries.
Example:
```ruby
pry(main)> Gitlab::UsageData.count(User.active)
(2.6ms) SELECT "features"."key" FROM "features"
(15.3ms) SELECT MIN("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4))
(2.4ms) SELECT MAX("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4))
(1.9ms) SELECT COUNT("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4)) AND "users"."id" BETWEEN 1 AND 100000
```
### 4. Optimize queries with #database-lab
Paste the SQL query into `#database-lab` to see how the query performs at scale.
- `#database-lab` is a Slack channel which uses a production-sized environment to test your queries.
- GitLab.com’s production database has a 15 second timeout.
- Any single query must stay below [1 second execution time](../query_performance.md#timing-guidelines-for-queries) with cold caches.
- Add a specialized index on columns involved to reduce the execution time.
In order to have an understanding of the query's execution we add in the MR description the following information:
- For counters that have a `time_period` test we add information for both cases:
- `time_period = {}` for all time periods
- `time_period = { created_at: 28.days.ago..Time.current }` for last 28 days period
- Execution plan and query time before and after optimization
- Query generated for the index and time
- Migration output for up and down execution
We also use `#database-lab` and [explain.depesz.com](https://explain.depesz.com/). For more details, see the [database review guide](../database_review.md#preparation-when-adding-or-modifying-queries).
#### Optimization recommendations and examples
- Use specialized indexes [example 1](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26871), [example 2](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26445).
- Use defined `start` and `finish`, and simple queries, because these values can be memoized and reused, [example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/37155).
- Avoid joins and write the queries as simply as possible, [example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/36316).
- Set a custom `batch_size` for `distinct_count`, [example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/38000).
### 5. Add the metric definition
When adding, changing, or updating metrics, please update the [Event Dictionary's **Usage Ping** table](https://about.gitlab.com/handbook/product/product-analytics-guide/#event-dictionary).
### 6. Add new metric to Versions Application
Check if new metrics need to be added to the Versions Application. See `usage_data` [schema](https://gitlab.com/gitlab-services/version-gitlab-com/-/blob/master/db/schema.rb#L147) and usage data [parameters accepted](https://gitlab.com/gitlab-services/version-gitlab-com/-/blob/master/app/services/usage_ping.rb). Any metrics added under the `counts` key are saved in the `stats` column.
### 7. Add the feature label
Add the `feature` label to the Merge Request for new Usage Ping metrics. These are user-facing changes and are part of expanding the Usage Ping feature.
### 8. Add a changelog file
Ensure you comply with the [Changelog entries guide](../changelog.md).
### 9. Ask for a Product Analytics Review
On GitLab.com, we have DangerBot setup to monitor Product Analytics related files and DangerBot recommends a Product Analytics review. Mention `@gitlab-org/growth/product_analytics/engineers` in your MR for a review.
### 10. Verify your metric
On GitLab.com, the Product Analytics team regularly monitors Usage Ping. They may alert you that your metrics need further optimization to run quicker and with greater success. You may also use the [Usage Ping QA dashboard](https://app.periscopedata.com/app/gitlab/632033/Usage-Ping-QA) to check how well your metric performs. The dashboard allows filtering by GitLab version, by "Self-managed" & "Saas" and shows you how many failures have occurred for each metric. Whenever you notice a high failure rate, you may re-optimize your metric.
### Optional: Test Prometheus based Usage Ping
If the data submitted includes metrics [queried from Prometheus](#prometheus-queries) that you would like to inspect and verify,
then you need to ensure that a Prometheus server is running locally, and that furthermore the respective GitLab components
are exporting metrics to it. If you do not need to test data coming from Prometheus, no further action
is necessary, since Usage Ping should degrade gracefully in the absence of a running Prometheus server.
There are currently three kinds of components that may export data to Prometheus, and which are included in Usage Ping:
- [`node_exporter`](https://github.com/prometheus/node_exporter) - Exports node metrics from the host machine
- [`gitlab-exporter`](https://gitlab.com/gitlab-org/gitlab-exporter) - Exports process metrics from various GitLab components
- various GitLab services such as Sidekiq and the Rails server that export their own metrics
#### Test with an Omnibus container
This is the recommended approach to test Prometheus based Usage Ping.
The easiest way to verify your changes is to build a new Omnibus image from your code branch via CI, then download the image
and run a local container instance:
1. From your merge request, click on the `qa` stage, then trigger the `package-and-qa` job. This job triggers an Omnibus
build in a [downstream pipeline of the `omnibus-gitlab-mirror` project](https://gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/-/pipelines).
1. In the downstream pipeline, wait for the `gitlab-docker` job to finish.
1. Open the job logs and locate the full container name including the version. It takes the following form: `registry.gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/gitlab-ee:<VERSION>`.
1. On your local machine, make sure you are logged in to the GitLab Docker registry. You can find the instructions for this in
[Authenticate to the GitLab Container Registry](../../user/packages/container_registry/index.md#authenticate-with-the-container-registry).
1. Once logged in, download the new image via `docker pull registry.gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/gitlab-ee:<VERSION>`
1. For more information about working with and running Omnibus GitLab containers in Docker, please refer to [GitLab Docker images](https://docs.gitlab.com/omnibus/docker/README.html) in the Omnibus documentation.
#### Test with GitLab development toolkits
This is the less recommended approach, since it comes with a number of difficulties when emulating a real GitLab deployment.
The [GDK](https://gitlab.com/gitlab-org/gitlab-development-kit) is not currently set up to run a Prometheus server or `node_exporter` alongside other GitLab components. If you would
like to do so, [Monitoring the GDK with Prometheus](https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/master/doc/howto/prometheus/index.md#monitoring-the-gdk-with-prometheus) is a good start.
The [GCK](https://gitlab.com/gitlab-org/gitlab-compose-kit) has limited support for testing Prometheus based Usage Ping.
By default, it already comes with a fully configured Prometheus service that is set up to scrape a number of components,
but with the following limitations:
- It does not currently run a `gitlab-exporter` instance, so several `process_*` metrics from services such as Gitaly may be missing.
- While it runs a `node_exporter`, `docker-compose` services emulate hosts, meaning that it would normally report itself to not be associated
with any of the other services that are running. That is not how node metrics are reported in a production setup, where `node_exporter`
always runs as a process alongside other GitLab components on any given node. From Usage Ping's perspective none of the node data would therefore
appear to be associated to any of the services running, since they all appear to be running on different hosts. To alleviate this problem, the `node_exporter` in GCK was arbitrarily "assigned" to the `web` service, meaning only for this service `node_*` metrics appears in Usage Ping.
## Aggregated metrics
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/45979) in GitLab 13.6.
WARNING:
This feature is intended solely for internal GitLab use.
In order to add data for aggregated metrics into Usage Ping payload you should add corresponding definition in [`aggregated_metrics`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/aggregated_metrics/). Each aggregate definition includes following parts:
- name: unique name under which aggregate metric is added to Usage Ping payload
- operator: operator that defines how aggregated metric data is counted. Available operators are:
- `OR`: removes duplicates and counts all entries that triggered any of listed events
- `AND`: removes duplicates and counts all elements that were observed triggering all of following events
- events: list of events names (from [`known_events/`](#known-events-are-added-automatically-in-usage-data-payload)) to aggregate into metric. All events in this list must have the same `redis_slot` and `aggregation` attributes.
- feature_flag: name of [development feature flag](../feature_flags/development.md#development-type) that is checked before
metrics aggregation is performed. Corresponding feature flag should have `default_enabled` attribute set to `false`.
`feature_flag` attribute is **OPTIONAL** and can be omitted, when `feature_flag` is missing no feature flag is checked.
Example aggregated metric entries:
```yaml
- name: product_analytics_test_metrics_union
operator: OR
events: ['i_search_total', 'i_search_advanced', 'i_search_paid']
- name: product_analytics_test_metrics_intersection_with_feautre_flag
operator: AND
events: ['i_search_total', 'i_search_advanced', 'i_search_paid']
feature_flag: example_aggregated_metric
```
Aggregated metrics are added under `aggregated_metrics` key in both `counts_weekly` and `counts_monthly` top level keys in Usage Ping payload.
```ruby
{
:counts_monthly => {
:deployments => 1003,
:successful_deployments => 78,
:failed_deployments => 275,
:packages => 155,
:personal_snippets => 2106,
:project_snippets => 407,
:promoted_issues => 719,
:aggregated_metrics => {
:product_analytics_test_metrics_union => 7,
:product_analytics_test_metrics_intersection_with_feautre_flag => 2
},
:snippets => 2513
}
}
```

## Notable changes
In GitLab 13.5, `pg_system_id` was added to send the [PostgreSQL system identifier](https://www.2ndquadrant.com/en/blog/support-for-postgresqls-system-identifier-in-barman/).
## Exporting Usage Ping SQL queries and definitions
Two Rake tasks exist to export Usage Ping definitions.
- The Rake tasks export the raw SQL queries for `count`, `distinct_count`, `sum`.
- The Rake tasks export the Redis counter class or the line of the Redis block for `redis_usage_data`.
- The Rake tasks calculate the `alt_usage_data` metrics.
In the home directory of your local GitLab installation run the following Rake tasks for the YAML and JSON versions respectively:
```shell
# for YAML export
bin/rake gitlab:usage_data:dump_sql_in_yaml
# for JSON export
bin/rake gitlab:usage_data:dump_sql_in_json
# You may pipe the output into a file
bin/rake gitlab:usage_data:dump_sql_in_yaml > ~/Desktop/usage-metrics-2020-09-02.yaml
```
## Generating and troubleshooting usage ping
To get a usage ping, or to troubleshoot caching issues on your GitLab instance, please follow [instructions to generate usage ping](../../administration/troubleshooting/gitlab_rails_cheat_sheet.md#generate-usage-ping).

# Snowplow Guide
This guide provides an overview of how Snowplow works, and implementation details.

## What is Snowplow
Snowplow is an enterprise-grade marketing and Product Intelligence platform which helps track the way users engage with our website and application.
[Snowplow](https://github.com/snowplow/snowplow) consists of the following loosely-coupled sub-systems:
- **Trackers** fire Snowplow events. Snowplow has 12 trackers, covering web, mobile, desktop, server, and IoT.
- **Collectors** receive Snowplow events from trackers. We have three different event collectors, synchronizing events either to Amazon S3, Apache Kafka, or Amazon Kinesis.
- **Enrich** cleans up the raw Snowplow events, enriches them and puts them into storage. We have an Hadoop-based enrichment process, and a Kinesis-based or Kafka-based process.
- **Storage** is where the Snowplow events live. We store the Snowplow events in a flat file structure on S3, and in the Redshift and PostgreSQL databases.
- **Data modeling** is where event-level data is joined with other data sets and aggregated into smaller data sets, and business logic is applied. This produces a clean set of tables which make it easier to perform analysis on the data. We have data models for Redshift and Looker.
- **Analytics** are performed on the Snowplow events or on the aggregate tables.
![snowplow_flow](img/snowplow_flow.png)
## Snowplow schema
We have many definitions of Snowplow's schema. We have an active issue to [standardize this schema](https://gitlab.com/gitlab-org/gitlab/-/issues/207930) including the following definitions:
- Frontend and backend taxonomy as listed below
- [Structured event taxonomy](#structured-event-taxonomy)
- [Self describing events](https://github.com/snowplow/snowplow/wiki/Custom-events#self-describing-events)
- [Iglu schema](https://gitlab.com/gitlab-org/iglu/)
- [Snowplow authored events](https://github.com/snowplow/snowplow/wiki/Snowplow-authored-events)
## Enabling Snowplow
Tracking can be enabled at:
- The instance level, which enables tracking on both the frontend and backend layers.
- User level, though user tracking can be disabled on a per-user basis. GitLab tracking respects the [Do Not Track](https://www.eff.org/issues/do-not-track) standard, so any user who has enabled the Do Not Track option in their browser is not tracked at a user level.
We use Snowplow for the majority of our tracking strategy and it is enabled on GitLab.com. On a self-managed instance, Snowplow can be enabled by navigating to:
- **Admin Area > Settings > General** in the UI.
- `admin/application_settings/integrations` in your browser.
The following configuration is required:
| Name | Value |
|---------------|---------------------------|
| Collector | `snowplow.trx.gitlab.net` |
| Site ID | `gitlab` |
| Cookie domain | `.gitlab.com` |
## Snowplow request flow
The following example shows a basic request/response flow between the following components:
- Snowplow JS / Ruby Trackers on GitLab.com
- [GitLab.com Snowplow Collector](https://gitlab.com/gitlab-com/gl-infra/readiness/-/blob/master/library/snowplow/index.md)
- The GitLab S3 Bucket
- The GitLab Snowflake Data Warehouse

## Structured event taxonomy
When adding new click events, we should add them in a way that's internally consistent. If we don't, it is very painful to perform analysis across features since each feature captures events differently.
The current method provides several attributes that are sent on each click event. Please try to follow these guidelines when specifying events to capture:
| attribute | type | required | description |
| --------- | ------- | -------- | ----------- |
| category | text | true | The page or backend area of the application. Unless infeasible, please use the Rails page attribute by default in the frontend, and namespace + classname on the backend. |
| action | text | true | The action the user is taking, or aspect that's being instrumented. The first word should always describe the action or aspect: clicks should be `click`, activations should be `activate`, creations should be `create`, etc. Use underscores to describe what was acted on; for example, activating a form field would be `activate_form_input`. An interface action like clicking on a dropdown would be `click_dropdown`, while a behavior like creating a project record from the backend would be `create_project` |
| label | text | false | The specific element, or object that's being acted on. This is either the label of the element (e.g. a tab labeled 'Create from template' may be `create_from_template`) or a unique identifier if no text is available (e.g. closing the Groups dropdown in the top navbar might be `groups_dropdown_close`), or it could be the name or title attribute of a record being created. |
| property | text | false | Any additional property of the element, or object being acted on. |
| value | decimal | false | Describes a numeric value or something directly related to the event. This could be the value of an input (e.g. `10` when clicking `internal` visibility). |
### Web-specific parameters
Snowplow JS adds many [web-specific parameters](https://docs.snowplowanalytics.com/docs/collecting-data/collecting-from-own-applications/snowplow-tracker-protocol/#Web-specific_parameters) to all web events by default.
## Implementing Snowplow JS (Frontend) tracking
GitLab provides `Tracking`, an interface that wraps the [Snowplow JavaScript Tracker](https://github.com/snowplow/snowplow/wiki/javascript-tracker) for tracking custom events. There are a few ways to use tracking, but each generally requires at minimum, a `category` and an `action`. Additional data can be provided that adheres to our [Structured event taxonomy](#structured-event-taxonomy).
| field | type | default value | description |
|:-----------|:-------|:---------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `category` | string | document.body.dataset.page | Page or subsection of a page that events are being captured within. |
| `action` | string | 'generic' | Action the user is taking. Clicks should be `click` and activations should be `activate`, so for example, focusing a form field would be `activate_form_input`, and clicking a button would be `click_button`. |
| `data` | object | {} | Additional data such as `label`, `property`, `value`, and `context` as described in our [Structured event taxonomy](#structured-event-taxonomy). |
### Tracking in HAML (or Vue Templates)
When working within HAML (or Vue templates) we can add `data-track-*` attributes to elements of interest. All elements that have a `data-track-event` attribute automatically have event tracking bound on clicks.
Below is an example of `data-track-*` attributes assigned to a button:
```haml
%button.btn{ data: { track: { event: "click_button", label: "template_preview", property: "my-template" } } }
```
```html
<button class="btn"
data-track-event="click_button"
data-track-label="template_preview"
data-track-property="my-template"
/>
```
Event listeners are bound at the document level to handle click events on or within elements with these data attributes. This allows them to be properly handled on re-rendering and changes to the DOM. Note that because of the way these events are bound, click events should not be stopped from propagating up the DOM tree. If for any reason click events are being stopped from propagating, you need to implement your own listeners and follow the instructions in [Tracking in raw JavaScript](#tracking-in-raw-javascript).
Below is a list of supported `data-track-*` attributes:
| attribute | required | description |
|:----------------------|:---------|:------------|
| `data-track-event` | true | Action the user is taking. Clicks must be prepended with `click` and activations must be prepended with `activate`. For example, focusing a form field would be `activate_form_input` and clicking a button would be `click_button`. |
| `data-track-label` | false | The `label` as described in our [Structured event taxonomy](#structured-event-taxonomy). |
| `data-track-property` | false | The `property` as described in our [Structured event taxonomy](#structured-event-taxonomy). |
| `data-track-value` | false | The `value` as described in our [Structured event taxonomy](#structured-event-taxonomy). If omitted, this is the element's `value` property or an empty string. For checkboxes, the default value is the element's checked attribute or `false` when unchecked. |
| `data-track-context` | false | The `context` as described in our [Structured event taxonomy](#structured-event-taxonomy). |
#### Caveats
When using the GitLab helper method [`nav_link`](https://gitlab.com/gitlab-org/gitlab/-/blob/898b286de322e5df6a38d257b10c94974d580df8/app/helpers/tab_helper.rb#L69) be sure to wrap `html_options` under the `html_options` keyword argument.
Be careful, as this behavior can be confused with the `ActionView` helper method [`link_to`](https://api.rubyonrails.org/v5.2.3/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to) that does not require additional wrapping of `html_options`
`nav_link(controller: ['dashboard/groups', 'explore/groups'], html_options: { data: { track_label: "groups_dropdown", track_event: "click_dropdown" } })`
vs
`link_to assigned_issues_dashboard_path, title: _('Issues'), data: { track_label: 'main_navigation', track_event: 'click_issues_link' }`
### Tracking within Vue components
There's a tracking Vue mixin that can be used in components if more complex tracking is required. To use it, first import the `Tracking` library and request a mixin.
```javascript
import Tracking from '~/tracking';
const trackingMixin = Tracking.mixin({ label: 'right_sidebar' });
```
You can provide default options that are passed along whenever an event is tracked from within your component. For instance, if all events within a component should be tracked with a given `label`, you can provide one at this time. Available defaults are `category`, `label`, `property`, and `value`. If no category is specified, `document.body.dataset.page` is used as the default.
You can then use the mixin normally in your component with the `mixin` Vue declaration. The mixin also provides the ability to specify tracking options in `data` or `computed`. These override any defaults and allow the values to be dynamic from props, or based on state.
```javascript
export default {
mixins: [trackingMixin],
// ...[component implementation]...
data() {
return {
expanded: false,
tracking: {
label: 'left_sidebar'
}
};
},
}
```
The mixin provides a `track` method that can be called within the template, or from component methods. An example of the whole implementation might look like the following.
```javascript
export default {
mixins: [Tracking.mixin({ label: 'right_sidebar' })],
data() {
return {
expanded: false,
};
},
methods: {
toggle() {
this.expanded = !this.expanded;
this.track('click_toggle', { value: this.expanded })
}
}
};
```
And if needed within the template, you can use the `track` method directly as well.
```html
<template>
<div>
<a class="toggle" @click.prevent="toggle">Toggle</a>
<div v-if="expanded">
<p>Hello world!</p>
<a @click.prevent="track('click_action')">Track an event</a>
</div>
</div>
</template>
```
### Tracking in raw JavaScript
Custom event tracking and instrumentation can be added by directly calling the `Tracking.event` static function. The following example demonstrates tracking a click on a button by calling `Tracking.event` manually.
```javascript
import Tracking from '~/tracking';
const button = document.getElementById('create_from_template_button');
button.addEventListener('click', () => {
Tracking.event('dashboard:projects:index', 'click_button', {
label: 'create_from_template',
property: 'template_preview',
value: 'rails',
});
})
```
### Tests and test helpers
In Jest particularly in Vue tests, you can use the following:
```javascript
import { mockTracking } from 'helpers/tracking_helper';
describe('MyTracking', () => {
let spy;
beforeEach(() => {
spy = mockTracking('_category_', wrapper.element, jest.spyOn);
});
it('tracks an event when clicked on feedback', () => {
wrapper.find('.discover-feedback-icon').trigger('click');
expect(spy).toHaveBeenCalledWith('_category_', 'click_button', {
label: 'security-discover-feedback-cta',
property: '0',
});
});
});
```
In obsolete Karma tests it's used as below:
```javascript
import { mockTracking, triggerEvent } from 'spec/helpers/tracking_helper';
describe('my component', () => {
let trackingSpy;
beforeEach(() => {
trackingSpy = mockTracking('_category_', vm.$el, spyOn);
});
const triggerEvent = () => {
// action which should trigger a event
};
it('tracks an event when toggled', () => {
expect(trackingSpy).not.toHaveBeenCalled();
triggerEvent('a.toggle');
expect(trackingSpy).toHaveBeenCalledWith('_category_', 'click_edit_button', {
label: 'right_sidebar',
property: 'confidentiality',
});
});
});
```
## Implementing Snowplow Ruby (Backend) tracking
GitLab provides `Gitlab::Tracking`, an interface that wraps the [Snowplow Ruby Tracker](https://github.com/snowplow/snowplow/wiki/ruby-tracker) for tracking custom events.
Custom event tracking and instrumentation can be added by directly calling the `GitLab::Tracking.event` class method, which accepts the following arguments:
| argument | type | default value | description |
|:-----------|:-------|:--------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `category` | string | 'application' | Area or aspect of the application. This could be `HealthCheckController` or `Lfs::FileTransformer` for instance. |
| `action` | string | 'generic' | The action being taken, which can be anything from a controller action like `create` to something like an Active Record callback. |
| `data` | object | {} | Additional data such as `label`, `property`, `value`, and `context` as described in [Structured event taxonomy](#structured-event-taxonomy). These are set as empty strings if you don't provide them. |
Tracking can be viewed as either tracking user behavior, or can be used for instrumentation to monitor and visualize performance over time in an area or aspect of code.
For example:
```ruby
class Projects::CreateService < BaseService
def execute
project = Project.create(params)
Gitlab::Tracking.event('Projects::CreateService', 'create_project',
label: project.errors.full_messages.to_sentence,
value: project.valid?
)
end
end
```
### Unit testing
Use the `expect_snowplow_event` helper when testing backend Snowplow events. See [testing best practices](
https://docs.gitlab.com/ee/development/testing_guide/best_practices.html#test-snowplow-events) for details.
### Performance
We use the [AsyncEmitter](https://github.com/snowplow/snowplow/wiki/Ruby-Tracker#52-the-asyncemitter-class) when tracking events, which allows for instrumentation calls to be run in a background thread. This is still an active area of development.
## Developing and testing Snowplow
There are several tools for developing and testing Snowplow Event
| Testing Tool | Frontend Tracking | Backend Tracking | Local Development Environment | Production Environment | Production Environment |

### Preparing your MR for Review
1. For frontend events, in the MR description section, add a screenshot of the event's relevant section using the [Snowplow Analytics Debugger](https://chrome.google.com/webstore/detail/snowplow-analytics-debugg/jbnlcgeengmijcghameodeaenefieedm) Chrome browser extension.
1. For backend events, please use Snowplow Micro and add the output of the Snowplow Micro good events `GET http://localhost:9090/micro/good`.
### Snowplow Analytics Debugger Chrome Extension
Snowplow Analytics Debugger is a browser extension for testing frontend events. This works on production, staging and local development environments.
1. Install the [Snowplow Analytics Debugger](https://chrome.google.com/webstore/detail/snowplow-analytics-debugg/jbnlcgeengmijcghameodeaenefieedm) Chrome browser extension.
1. Open Chrome DevTools to the Snowplow Analytics Debugger tab.
1. Learn more at [Igloo Analytics](https://www.iglooanalytics.com/blog/snowplow-analytics-debugger-chrome-extension.html).
### Snowplow Inspector Chrome Extension
Snowplow Inspector Chrome Extension is a browser extension for testing frontend events. This works on production, staging and local development environments.
1. Install [Snowplow Inspector](https://chrome.google.com/webstore/detail/snowplow-inspector/maplkdomeamdlngconidoefjpogkmljm?hl=en).
1. Open the Chrome extension by pressing the Snowplow Inspector icon beside the address bar.
1. Click around on a webpage with Snowplow and you should see JavaScript events firing in the inspector window.
### Snowplow Micro
Snowplow Micro is a very small version of a full Snowplow data collection pipeline: small enough that it can be launched by a test suite. Events can be recorded into Snowplow Micro just as they can a full Snowplow pipeline. Micro then exposes an API that can be queried.
Snowplow Micro is a Docker-based solution for testing frontend and backend events in a local development environment. You need to modify GDK using the instructions below to set this up.
- Read [Introducing Snowplow Micro](https://snowplowanalytics.com/blog/2019/07/17/introducing-snowplow-micro/)
- Look at the [Snowplow Micro repository](https://github.com/snowplow-incubator/snowplow-micro)
- Watch our [installation guide recording](https://www.youtube.com/watch?v=OX46fo_A0Ag)
1. Ensure Docker is installed and running.
1. Install [Snowplow Micro](https://github.com/snowplow-incubator/snowplow-micro) by cloning the settings in [this project](https://gitlab.com/gitlab-org/snowplow-micro-configuration):
1. Navigate to the directory with the cloned project, and start the appropriate Docker
container with the following script:
```shell
./snowplow-micro.sh
```
1. Update your instance's settings to enable Snowplow events and point to the Snowplow Micro collector:
```shell
gdk psql -d gitlabhq_development
update application_settings set snowplow_collector_hostname='localhost:9090', snowplow_enabled=true, snowplow_cookie_domain='.gitlab.com';
```
1. Update `DEFAULT_SNOWPLOW_OPTIONS` in `app/assets/javascripts/tracking.js` to remove `forceSecureTracker: true`:
```diff

```
1. Restart GDK:
```shell
`gdk restart`
```
1. Send a test Snowplow event from the Rails console:
```ruby
Gitlab::Tracking.self_describing_event('iglu:com.gitlab/pageview_context/jsonschema/1-0-0', data: { page_type: 'MY_TYPE' }, context: nil)
```
1. Navigate to `localhost:9090/micro/good` to see the event.
### Snowplow Mini
[Snowplow Mini](https://github.com/snowplow/snowplow-mini) is an easily-deployable, single-instance version of Snowplow.
Snowplow Mini can be used for testing frontend and backend events on a production, staging and local development environment.
For GitLab.com, we're setting up a [QA and Testing environment](https://gitlab.com/gitlab-org/telemetry/-/issues/266) using Snowplow Mini.

# Usage Ping Guide
> - Introduced in GitLab Enterprise Edition 8.10.
> - More statistics were added in GitLab Enterprise Edition 8.12.
> - Moved to GitLab Core in 9.1.
> - More statistics were added in GitLab Ultimate 11.2.
This guide describes Usage Ping's purpose and how it's implemented.
For more information about Product Intelligence, see:
- [Product Intelligence Guide](https://about.gitlab.com/handbook/product/product-intelligence-guide/)
- [Snowplow Guide](snowplow.md)
More useful links:

- [Data for Product Managers](https://about.gitlab.com/handbook/business-ops/data-team/programs/data-for-product-managers/)
- [Data Infrastructure](https://about.gitlab.com/handbook/business-ops/data-team/platform/infrastructure/)
## What is Usage Ping?
- GitLab sends a weekly payload containing usage data to GitLab Inc. Usage Ping provides high-level data to help our product, support, and sales teams. It does not send any project names, usernames, or any other specific data. The information from the usage ping is not anonymous, it is linked to the hostname of the instance. Sending usage ping is optional, and any instance can disable analytics.
- The usage data is primarily composed of row counts for different tables in the instance’s database. By comparing these counts month over month (or week over week), we can get a rough sense for how an instance is using the different features within the product. In addition to counts, other facts
that help us classify and understand GitLab installations are collected.
- Usage ping is important to GitLab as we use it to calculate our Stage Monthly Active Users (SMAU) which helps us measure the success of our stages and features.
- While usage ping is enabled, GitLab gathers data from the other instances and can show usage statistics of your instance to your users.
### Why should we enable Usage Ping?
- The main purpose of Usage Ping is to build a better GitLab. Data about how GitLab is used is collected to better understand feature/stage adoption and usage, which helps us understand how GitLab is adding value and helps our team better understand the reasons why people use GitLab and with this knowledge we're able to make better product decisions.
- As a benefit of having the usage ping active, GitLab lets you analyze the users’ activities over time of your GitLab installation.
- As a benefit of having the usage ping active, GitLab provides you with The DevOps Report,which gives you an overview of your entire instance’s adoption of Concurrent DevOps from planning to monitoring.
- You get better, more proactive support. (assuming that our TAMs and support organization used the data to deliver more value)
- You get insight and advice into how to get the most value out of your investment in GitLab. Wouldn't you want to know that a number of features or values are not being adopted in your organization?
- You get a report that illustrates how you compare against other similar organizations (anonymized), with specific advice and recommendations on how to improve your DevOps processes.
- Usage Ping is enabled by default. To disable it, see [Disable Usage Ping](#disable-usage-ping).
### Limitations
- Usage Ping does not track frontend events things like page views, link clicks, or user sessions, and only focuses on aggregated backend events.
- Because of these limitations we recommend instrumenting your products with Snowplow for more detailed analytics on GitLab.com and use Usage Ping to track aggregated backend events on self-managed.
## Usage Ping payload
You can view the exact JSON payload sent to GitLab Inc. in the administration panel. To view the payload:
1. Navigate to **Admin Area > Settings > Metrics and profiling**.
1. Expand the **Usage statistics** section.
1. Click the **Preview payload** button.
For an example payload, see [Example Usage Ping payload](#example-usage-ping-payload).
## Disable Usage Ping
To disable Usage Ping in the GitLab UI, go to the **Settings** page of your administration panel and uncheck the **Usage Ping** checkbox.
To disable Usage Ping and prevent it from being configured in the future through the administration panel, Omnibus installs can set the following in [`gitlab.rb`](https://docs.gitlab.com/omnibus/settings/configuration.html#configuration-options):
```ruby
gitlab_rails['usage_ping_enabled'] = false
```
Source installations can set the following in `gitlab.yml`:
```yaml
production: &base
# ...
gitlab:
# ...
usage_ping_enabled: false
```
## Usage Ping request flow
The following example shows a basic request/response flow between a GitLab instance, the Versions Application, the License Application, Salesforce, the GitLab S3 Bucket, the GitLab Snowflake Data Warehouse, and Sisense:
```mermaid
sequenceDiagram
participant GitLab Instance
participant Versions Application
participant Licenses Application
participant Salesforce
participant S3 Bucket
participant Snowflake DW
participant Sisense Dashboards
GitLab Instance->>Versions Application: Send Usage Ping
loop Process usage data
Versions Application->>Versions Application: Parse usage data
Versions Application->>Versions Application: Write to database
Versions Application->>Versions Application: Update license ping time
end
loop Process data for Salesforce
Versions Application-xLicenses Application: Request Zuora subscription id
Licenses Application-xVersions Application: Zuora subscription id
Versions Application-xSalesforce: Request Zuora account id by Zuora subscription id
Salesforce-xVersions Application: Zuora account id
Versions Application-xSalesforce: Usage data for the Zuora account
end
Versions Application->>S3 Bucket: Export Versions database
S3 Bucket->>Snowflake DW: Import data
Snowflake DW->>Snowflake DW: Transform data using dbt
Snowflake DW->>Sisense Dashboards: Data available for querying
Versions Application->>GitLab Instance: DevOps Report (Conversational Development Index)
```
## How Usage Ping works
1. The Usage Ping [cron job](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/workers/gitlab_usage_ping_worker.rb#L30) is set in Sidekiq to run weekly.
1. When the cron job runs, it calls [`Gitlab::UsageData.to_json`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/submit_usage_ping_service.rb#L22).
1. `Gitlab::UsageData.to_json` [cascades down](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb#L22) to ~400+ other counter method calls.
1. The response of all methods calls are [merged together](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb#L14) into a single JSON payload in `Gitlab::UsageData.to_json`.
1. The JSON payload is then [posted to the Versions application]( https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/submit_usage_ping_service.rb#L20)
If a firewall exception is needed, the required URL depends on several things. If
the hostname is `version.gitlab.com`, the protocol is `TCP`, and the port number is `443`,
the required URL is <https://version.gitlab.com/>.
## Implementing Usage Ping
Usage Ping consists of two kinds of data, counters and observations. Counters track how often a certain event
happened over time, such as how many CI pipelines have run. They are monotonic and always trend up.
Observations are facts collected from one or more GitLab instances and can carry arbitrary data. There are no
general guidelines around how to collect those, due to the individual nature of that data.
There are several types of counters which are all found in `usage_data.rb`:
- **Ordinary Batch Counters:** Simple count of a given ActiveRecord_Relation
- **Distinct Batch Counters:** Distinct count of a given ActiveRecord_Relation on given column
- **Sum Batch Counters:** Sum the values of a given ActiveRecord_Relation on given column
- **Alternative Counters:** Used for settings and configurations
- **Redis Counters:** Used for in-memory counts.
NOTE:
Only use the provided counter methods. Each counter method contains a built in fail safe to isolate each counter to avoid breaking the entire Usage Ping.
### Why batch counting
For large tables, PostgreSQL can take a long time to count rows due to MVCC [(Multi-version Concurrency Control)](https://en.wikipedia.org/wiki/Multiversion_concurrency_control). Batch counting is a counting method where a single large query is broken into multiple smaller queries. For example, instead of a single query querying 1,000,000 records, with batch counting, you can execute 100 queries of 10,000 records each. Batch counting is useful for avoiding database timeouts as each batch query is significantly shorter than one single long running query.
For GitLab.com, there are extremely large tables with 15 second query timeouts, so we use batch counting to avoid encountering timeouts. Here are the sizes of some GitLab.com tables:
| Table | Row counts in millions |
|------------------------------|------------------------|
| `merge_request_diff_commits` | 2280 |
| `ci_build_trace_sections` | 1764 |
| `merge_request_diff_files` | 1082 |
| `events` | 514 |
There are two batch counting methods provided, `Ordinary Batch Counters` and `Distinct Batch Counters`. Batch counting requires indexes on columns to calculate max, min, and range queries. In some cases, a specialized index may need to be added on the columns involved in a counter.
### Ordinary Batch Counters
Handles `ActiveRecord::StatementInvalid` error
Simple count of a given ActiveRecord_Relation, does a non-distinct batch count, smartly reduces batch_size and handles errors.
Method: `count(relation, column = nil, batch: true, start: nil, finish: nil)`
Arguments:
- `relation` the ActiveRecord_Relation to perform the count
- `column` the column to perform the count on, by default is the primary key
- `batch`: default `true` in order to use batch counting
- `start`: custom start of the batch counting in order to avoid complex min calculations
- `end`: custom end of the batch counting in order to avoid complex min calculations
Examples:
```ruby
count(User.active)
count(::Clusters::Cluster.aws_installed.enabled, :cluster_id)
count(::Clusters::Cluster.aws_installed.enabled, :cluster_id, start: ::Clusters::Cluster.minimum(:id), finish: ::Clusters::Cluster.maximum(:id))
```
### Distinct Batch Counters
Handles `ActiveRecord::StatementInvalid` error
Distinct count of a given ActiveRecord_Relation on given column, a distinct batch count, smartly reduces batch_size and handles errors.
Method: `distinct_count(relation, column = nil, batch: true, batch_size: nil, start: nil, finish: nil)`
Arguments:
- `relation` the ActiveRecord_Relation to perform the count
- `column` the column to perform the distinct count, by default is the primary key
- `batch`: default `true` in order to use batch counting
- `batch_size`: if none set it uses default value 10000 from `Gitlab::Database::BatchCounter`
- `start`: custom start of the batch counting in order to avoid complex min calculations
- `end`: custom end of the batch counting in order to avoid complex min calculations
WARNING:
Counting over non-unique columns can lead to performance issues. Take a look at the [iterating tables in batches](iterating_tables_in_batches.md) guide for more details.
Examples:
```ruby
distinct_count(::Project, :creator_id)
distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::User.minimum(:id), finish: ::User.maximum(:id))
distinct_count(::Clusters::Applications::CertManager.where(time_period).available.joins(:cluster), 'clusters.user_id')
```
### Sum Batch Counters
Handles `ActiveRecord::StatementInvalid` error
Sum the values of a given ActiveRecord_Relation on given column and handles errors.
Method: `sum(relation, column, batch_size: nil, start: nil, finish: nil)`
Arguments:
- `relation` the ActiveRecord_Relation to perform the operation
- `column` the column to sum on
- `batch_size`: if none set it uses default value 1000 from `Gitlab::Database::BatchCounter`
- `start`: custom start of the batch counting in order to avoid complex min calculations
- `end`: custom end of the batch counting in order to avoid complex min calculations
Examples:
```ruby
sum(JiraImportState.finished, :imported_issues_count)
```
### Grouping & Batch Operations
The `count`, `distinct_count`, and `sum` batch counters can accept an `ActiveRecord::Relation`
object, which groups by a specified column. With a grouped relation, the methods do batch counting,
handle errors, and returns a hash table of key-value pairs.
Examples:
```ruby
count(Namespace.group(:type))
# returns => {nil=>179, "Group"=>54}
distinct_count(Project.group(:visibility_level), :creator_id)
# returns => {0=>1, 10=>1, 20=>11}
sum(Issue.group(:state_id), :weight))
# returns => {1=>3542, 2=>6820}
```
### Redis Counters
Handles `::Redis::CommandError` and `Gitlab::UsageDataCounters::BaseCounter::UnknownEvent`
returns -1 when a block is sent or hash with all values -1 when a `counter(Gitlab::UsageDataCounters)` is sent
different behavior due to 2 different implementations of Redis counter
Method: `redis_usage_data(counter, &block)`
Arguments:
- `counter`: a counter from `Gitlab::UsageDataCounters`, that has `fallback_totals` method implemented
- or a `block`: which is evaluated
#### Ordinary Redis Counters
Examples of implementation:
- Using Redis methods [`INCR`](https://redis.io/commands/incr), [`GET`](https://redis.io/commands/get), and [`Gitlab::UsageDataCounters::WikiPageCounter`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/wiki_page_counter.rb)
- Using Redis methods [`HINCRBY`](https://redis.io/commands/hincrby), [`HGETALL`](https://redis.io/commands/hgetall), and [`Gitlab::UsageCounters::PodLogs`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_counters/pod_logs.rb)
##### UsageData API Tracking
<!-- There's nearly identical content in `##### Adding new events`. If you fix errors here, you may need to fix the same errors in the other location. -->
1. Track event using `UsageData` API
Increment event count using ordinary Redis counter, for given event name.
Tracking events using the `UsageData` API requires the `usage_data_api` feature flag to be enabled, which is enabled by default.
API requests are protected by checking for a valid CSRF token.
In order to be able to increment the values the related feature `usage_data_<event_name>` should be enabled.
```plaintext
POST /usage_data/increment_counter
```
| Attribute | Type | Required | Description |
| :-------- | :--- | :------- | :---------- |
| `event` | string | yes | The event name it should be tracked |
Response
- `200` if event was tracked
- `400 Bad request` if event parameter is missing
- `401 Unauthorized` if user is not authenticated
- `403 Forbidden` for invalid CSRF token provided
1. Track events using JavaScript/Vue API helper which calls the API above
Note that `usage_data_api` and `usage_data_#{event_name}` should be enabled in order to be able to track events
```javascript
import api from '~/api';
api.trackRedisCounterEvent('my_already_defined_event_name'),
```
#### Redis HLL Counters
With `Gitlab::UsageDataCounters::HLLRedisCounter` we have available data structures used to count unique values.
Implemented using Redis methods [PFADD](https://redis.io/commands/pfadd) and [PFCOUNT](https://redis.io/commands/pfcount).
##### Adding new events
1. Define events in [`known_events`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/).
Example event:
```yaml
- name: i_compliance_credential_inventory
category: compliance
redis_slot: compliance
expiry: 42 # 6 weeks
aggregation: weekly
```
Keys:
- `name`: unique event name.
Name format `<prefix>_<redis_slot>_name`.
Use one of the following prefixes for the event's name:
- `g_` for group, as an event which is tracked for group.
- `p_` for project, as an event which is tracked for project.
- `i_` for instance, as an event which is tracked for instance.
- `a_` for events encompassing all `g_`, `p_`, `i_`.
- `o_` for other.
Consider including in the event's name the Redis slot in order to be able to count totals for a specific category.
Example names: `i_compliance_credential_inventory`, `g_analytics_contribution`.
- `category`: event category. Used for getting total counts for events in a category, for easier
access to a group of events.
- `redis_slot`: optional Redis slot; default value: event name. Used if needed to calculate totals
for a group of metrics. Ensure keys are in the same slot. For example:
`i_compliance_credential_inventory` with `redis_slot: 'compliance'` builds Redis key
`i_{compliance}_credential_inventory-2020-34`. If `redis_slot` is not defined the Redis key will
be `{i_compliance_credential_inventory}-2020-34`.
- `expiry`: expiry time in days. Default: 29 days for daily aggregation and 6 weeks for weekly
aggregation.
- `aggregation`: may be set to a `:daily` or `:weekly` key. Defines how counting data is stored in Redis.
Aggregation on a `daily` basis does not pull more fine grained data.
- `feature_flag`: optional. For details, see our [GitLab internal Feature flags](feature_flags/) documentation.
1. Track event in controller using `RedisTracking` module with `track_redis_hll_event(*controller_actions, name:, feature:, feature_default_enabled: false)`.
Arguments:
- `controller_actions`: controller actions we want to track.
- `name`: event name.
- `feature`: feature name, all metrics we track should be under feature flag.
- `feature_default_enabled`: feature flag is disabled by default, set to `true` for it to be enabled by default.
Example usage:
```ruby
# controller
class ProjectsController < Projects::ApplicationController
include RedisTracking
skip_before_action :authenticate_user!, only: :show
track_redis_hll_event :index, :show, name: 'g_compliance_example_feature_visitors', feature: :compliance_example_feature, feature_default_enabled: true
def index
render html: 'index'
end
def new
render html: 'new'
end
def show
render html: 'show'
end
end
```
1. Track event in API using `increment_unique_values(event_name, values)` helper method.
In order to be able to track the event, Usage Ping must be enabled and the event feature `usage_data_<event_name>` must be enabled.
Arguments:
- `event_name`: event name.
- `values`: values counted, one value or array of values.
Example usage:
```ruby
get ':id/registry/repositories' do
repositories = ContainerRepositoriesFinder.new(
user: current_user, subject: user_group
).execute
increment_unique_values('i_list_repositories', current_user.id)
present paginate(repositories), with: Entities::ContainerRegistry::Repository, tags: params[:tags], tags_count: params[:tags_count]
end
```
1. Track event using `track_usage_event(event_name, values) in services and graphql
Increment unique values count using Redis HLL, for given event name.
Example:
[Track usage event for incident created in service](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/issues/update_service.rb)
[Track usage event for incident created in graphql](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/graphql/mutations/alert_management/update_alert_status.rb)
```ruby
track_usage_event(:incident_management_incident_created, current_user.id)
```
<!-- There's nearly identical content in `##### UsageData API Tracking`. If you find / fix errors here, you may need to fix errors in that section too. -->
1. Track event using `UsageData` API
Increment unique users count using Redis HLL, for given event name.
Tracking events using the `UsageData` API requires the `usage_data_api` feature flag to be enabled, which is enabled by default.
API requests are protected by checking for a valid CSRF token.
In order to increment the values, the related feature `usage_data_<event_name>` should be
set to `default_enabled: true`. For more information, see
[Feature flags in development of GitLab](feature_flags/index.md).
```plaintext
POST /usage_data/increment_unique_users
```
| Attribute | Type | Required | Description |
| :-------- | :--- | :------- | :---------- |
| `event` | string | yes | The event name it should be tracked |
Response
Return 200 if tracking failed for any reason.
- `200` if event was tracked or any errors
- `400 Bad request` if event parameter is missing
- `401 Unauthorized` if user is not authenticated
- `403 Forbidden` for invalid CSRF token provided
1. Track events using JavaScript/Vue API helper which calls the API above
Example usage for an existing event already defined in [known events](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/):
Usage Data API is behind `usage_data_api` feature flag which, as of GitLab 13.7, is
now set to `default_enabled: true`.
Each event tracked using Usage Data API is behind a feature flag `usage_data_#{event_name}` which should be `default_enabled: true`
```javascript
import api from '~/api';
api.trackRedisHllUserEvent('my_already_defined_event_name'),
```
1. Track event using base module `Gitlab::UsageDataCounters::HLLRedisCounter.track_event(event_name, values:)`.
Arguments:
- `event_name`: event name.
- `values`: One value or array of values we count. For example: user_id, visitor_id, user_ids.
1. Track event on context level using base module `Gitlab::UsageDataCounters::HLLRedisCounter.track_event_in_context(event_name, values:, context:)`.
Arguments:
- `event_name`: event name.
- `values`: values we count. For example: user_id, visitor_id.
- `context`: context value. Allowed values are `default`, `free`, `bronze`, `silver`, `gold`, `starter`, `premium`, `ultimate`
1. Get event data using `Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names:, start_date:, end_date:, context: '')`.
Arguments:
- `event_names`: the list of event names.
- `start_date`: start date of the period for which we want to get event data.
- `end_date`: end date of the period for which we want to get event data.
- `context`: context of the event. Allowed values are `default`, `free`, `bronze`, `silver`, `gold`, `starter`, `premium`, `ultimate`.
1. Testing tracking and getting unique events
Trigger events in rails console by using `track_event` method
```ruby
Gitlab::UsageDataCounters::HLLRedisCounter.track_event('g_compliance_audit_events', values: 1)
Gitlab::UsageDataCounters::HLLRedisCounter.track_event('g_compliance_audit_events', values: [2, 3])
```
Next, get the unique events for the current week.
```ruby
# Get unique events for metric for current_week
Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names: 'g_compliance_audit_events',
start_date: Date.current.beginning_of_week, end_date: Date.current.end_of_week)
```
##### Recommendations
We have the following recommendations for [Adding new events](#adding-new-events):
- Event aggregation: weekly.
- Key expiry time:
- Daily: 29 days.
- Weekly: 42 days.
- When adding new metrics, use a [feature flag](../operations/feature_flags.md) to control the impact.
- For feature flags triggered by another service, set `default_enabled: false`,
- Events can be triggered using the `UsageData` API, which helps when there are > 10 events per change
##### Enable/Disable Redis HLL tracking
Events are tracked behind [feature flags](feature_flags/index.md) due to concerns for Redis performance and scalability.
For a full list of events and corresponding feature flags see, [known_events](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/) files.
To enable or disable tracking for specific event within <https://gitlab.com> or <https://about.staging.gitlab.com>, run commands such as the following to
[enable or disable the corresponding feature](feature_flags/index.md).
```shell
/chatops run feature set <feature_name> true
/chatops run feature set <feature_name> false
```
##### Known events are added automatically in usage data payload
All events added in [`known_events/common.yml`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/common.yml) are automatically added to usage data generation under the `redis_hll_counters` key. This column is stored in [version-app as a JSON](https://gitlab.com/gitlab-services/version-gitlab-com/-/blob/master/db/schema.rb#L209).
For each event we add metrics for the weekly and monthly time frames, and totals for each where applicable:
- `#{event_name}_weekly`: Data for 7 days for daily [aggregation](#adding-new-events) events and data for the last complete week for weekly [aggregation](#adding-new-events) events.
- `#{event_name}_monthly`: Data for 28 days for daily [aggregation](#adding-new-events) events and data for the last 4 complete weeks for weekly [aggregation](#adding-new-events) events.
Redis HLL implementation calculates automatic total metrics, if there are more than one metric for the same category, aggregation and Redis slot.
- `#{category}_total_unique_counts_weekly`: Total unique counts for events in the same category for the last 7 days or the last complete week, if events are in the same Redis slot and we have more than one metric.
- `#{category}_total_unique_counts_monthly`: Total unique counts for events in same category for the last 28 days or the last 4 complete weeks, if events are in the same Redis slot and we have more than one metric.
Example of `redis_hll_counters` data:
```ruby
{:redis_hll_counters=>
{"compliance"=>
{"g_compliance_dashboard_weekly"=>0,
"g_compliance_dashboard_monthly"=>0,
"g_compliance_audit_events_weekly"=>0,
"g_compliance_audit_events_monthly"=>0,
"compliance_total_unique_counts_weekly"=>0,
"compliance_total_unique_counts_monthly"=>0},
"analytics"=>
{"g_analytics_contribution_weekly"=>0,
"g_analytics_contribution_monthly"=>0,
"g_analytics_insights_weekly"=>0,
"g_analytics_insights_monthly"=>0,
"analytics_total_unique_counts_weekly"=>0,
"analytics_total_unique_counts_monthly"=>0},
"ide_edit"=>
{"g_edit_by_web_ide_weekly"=>0,
"g_edit_by_web_ide_monthly"=>0,
"g_edit_by_sfe_weekly"=>0,
"g_edit_by_sfe_monthly"=>0,
"ide_edit_total_unique_counts_weekly"=>0,
"ide_edit_total_unique_counts_monthly"=>0},
"search"=>
{"i_search_total_weekly"=>0, "i_search_total_monthly"=>0, "i_search_advanced_weekly"=>0, "i_search_advanced_monthly"=>0, "i_search_paid_weekly"=>0, "i_search_paid_monthly"=>0, "search_total_unique_counts_weekly"=>0, "search_total_unique_counts_monthly"=>0},
"source_code"=>{"wiki_action_weekly"=>0, "wiki_action_monthly"=>0}
}
```
Example usage:
```ruby
# Redis Counters
redis_usage_data(Gitlab::UsageDataCounters::WikiPageCounter)
redis_usage_data { ::Gitlab::UsageCounters::PodLogs.usage_totals[:total] }
# Define events in common.yml https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/known_events/common.yml
# Tracking events
Gitlab::UsageDataCounters::HLLRedisCounter.track_event('expand_vulnerabilities', values: visitor_id)
# Get unique events for metric
redis_usage_data { Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names: 'expand_vulnerabilities', start_date: 28.days.ago, end_date: Date.current) }
```
### Alternative Counters
Handles `StandardError` and fallbacks into -1 this way not all measures fail if we encounter one exception.
Mainly used for settings and configurations.
Method: `alt_usage_data(value = nil, fallback: -1, &block)`
Arguments:
- `value`: a simple static value in which case the value is simply returned.
- or a `block`: which is evaluated
- `fallback: -1`: the common value used for any metrics that are failing.
Example of usage:
```ruby
alt_usage_data { Gitlab::VERSION }
alt_usage_data { Gitlab::CurrentSettings.uuid }
alt_usage_data(999)
```
### Prometheus Queries
In those cases where operational metrics should be part of Usage Ping, a database or Redis query is unlikely
to provide useful data. Instead, Prometheus might be more appropriate, since most GitLab architectural
components publish metrics to it that can be queried back, aggregated, and included as usage data.
NOTE:
Prometheus as a data source for Usage Ping is currently only available for single-node Omnibus installations
that are running the [bundled Prometheus](../administration/monitoring/prometheus/index.md) instance.
To query Prometheus for metrics, a helper method is available to `yield` a fully configured
`PrometheusClient`, given it is available as per the note above:
```ruby
with_prometheus_client do |client|
response = client.query('<your query>')
...
end
```
Please refer to [the `PrometheusClient` definition](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/prometheus_client.rb)
for how to use its API to query for data.
## Developing and testing Usage Ping
### 1. Naming and placing the metrics
Add the metric in one of the top level keys
- `license`: for license related metrics.
- `settings`: for settings related metrics.
- `counts_weekly`: for counters that have data for the most recent 7 days.
- `counts_monthly`: for counters that have data for the most recent 28 days.
- `counts`: for counters that have data for all time.
### 2. Use your Rails console to manually test counters
```ruby
# count
Gitlab::UsageData.count(User.active)
Gitlab::UsageData.count(::Clusters::Cluster.aws_installed.enabled, :cluster_id)
# count distinct
Gitlab::UsageData.distinct_count(::Project, :creator_id)
Gitlab::UsageData.distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::User.minimum(:id), finish: ::User.maximum(:id))
```
### 3. Generate the SQL query
Your Rails console returns the generated SQL queries.
Example:
```ruby
pry(main)> Gitlab::UsageData.count(User.active)
(2.6ms) SELECT "features"."key" FROM "features"
(15.3ms) SELECT MIN("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4))
(2.4ms) SELECT MAX("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4))
(1.9ms) SELECT COUNT("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4)) AND "users"."id" BETWEEN 1 AND 100000
```
### 4. Optimize queries with #database-lab
Paste the SQL query into `#database-lab` to see how the query performs at scale.
- `#database-lab` is a Slack channel which uses a production-sized environment to test your queries.
- GitLab.com’s production database has a 15 second timeout.
- Any single query must stay below [1 second execution time](query_performance.md#timing-guidelines-for-queries) with cold caches.
- Add a specialized index on columns involved to reduce the execution time.
In order to have an understanding of the query's execution we add in the MR description the following information:
- For counters that have a `time_period` test we add information for both cases:
- `time_period = {}` for all time periods
- `time_period = { created_at: 28.days.ago..Time.current }` for last 28 days period
- Execution plan and query time before and after optimization
- Query generated for the index and time
- Migration output for up and down execution
We also use `#database-lab` and [explain.depesz.com](https://explain.depesz.com/). For more details, see the [database review guide](database_review.md#preparation-when-adding-or-modifying-queries).
#### Optimization recommendations and examples
- Use specialized indexes [example 1](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26871), [example 2](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26445).
- Use defined `start` and `finish`, and simple queries, because these values can be memoized and reused, [example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/37155).
- Avoid joins and write the queries as simply as possible, [example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/36316).
- Set a custom `batch_size` for `distinct_count`, [example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/38000).
### 5. Add the metric definition
When adding, changing, or updating metrics, please update the [Event Dictionary's **Usage Ping** table](https://about.gitlab.com/handbook/product/product-intelligence-guide/#event-dictionary).
### 6. Add new metric to Versions Application
Check if new metrics need to be added to the Versions Application. See `usage_data` [schema](https://gitlab.com/gitlab-services/version-gitlab-com/-/blob/master/db/schema.rb#L147) and usage data [parameters accepted](https://gitlab.com/gitlab-services/version-gitlab-com/-/blob/master/app/services/usage_ping.rb). Any metrics added under the `counts` key are saved in the `stats` column.
### 7. Add the feature label
Add the `feature` label to the Merge Request for new Usage Ping metrics. These are user-facing changes and are part of expanding the Usage Ping feature.
### 8. Add a changelog file
Ensure you comply with the [Changelog entries guide](changelog.md).
### 9. Ask for a Product Intelligence Review
On GitLab.com, we have DangerBot setup to monitor Product Intelligence related files and DangerBot recommends a Product Intelligence review. Mention `@gitlab-org/growth/product_intelligence/engineers` in your MR for a review.
### 10. Verify your metric
On GitLab.com, the Product Intelligence team regularly monitors Usage Ping. They may alert you that your metrics need further optimization to run quicker and with greater success. You may also use the [Usage Ping QA dashboard](https://app.periscopedata.com/app/gitlab/632033/Usage-Ping-QA) to check how well your metric performs. The dashboard allows filtering by GitLab version, by "Self-managed" & "Saas" and shows you how many failures have occurred for each metric. Whenever you notice a high failure rate, you may re-optimize your metric.
### Optional: Test Prometheus based Usage Ping
If the data submitted includes metrics [queried from Prometheus](#prometheus-queries) that you would like to inspect and verify,
then you need to ensure that a Prometheus server is running locally, and that furthermore the respective GitLab components
are exporting metrics to it. If you do not need to test data coming from Prometheus, no further action
is necessary, since Usage Ping should degrade gracefully in the absence of a running Prometheus server.
There are currently three kinds of components that may export data to Prometheus, and which are included in Usage Ping:
- [`node_exporter`](https://github.com/prometheus/node_exporter) - Exports node metrics from the host machine
- [`gitlab-exporter`](https://gitlab.com/gitlab-org/gitlab-exporter) - Exports process metrics from various GitLab components
- various GitLab services such as Sidekiq and the Rails server that export their own metrics
#### Test with an Omnibus container
This is the recommended approach to test Prometheus based Usage Ping.
The easiest way to verify your changes is to build a new Omnibus image from your code branch via CI, then download the image
and run a local container instance:
1. From your merge request, click on the `qa` stage, then trigger the `package-and-qa` job. This job triggers an Omnibus
build in a [downstream pipeline of the `omnibus-gitlab-mirror` project](https://gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/-/pipelines).
1. In the downstream pipeline, wait for the `gitlab-docker` job to finish.
1. Open the job logs and locate the full container name including the version. It takes the following form: `registry.gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/gitlab-ee:<VERSION>`.
1. On your local machine, make sure you are logged in to the GitLab Docker registry. You can find the instructions for this in
[Authenticate to the GitLab Container Registry](../user/packages/container_registry/index.md#authenticate-with-the-container-registry).
1. Once logged in, download the new image via `docker pull registry.gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/gitlab-ee:<VERSION>`
1. For more information about working with and running Omnibus GitLab containers in Docker, please refer to [GitLab Docker images](https://docs.gitlab.com/omnibus/docker/README.html) in the Omnibus documentation.
#### Test with GitLab development toolkits
This is the less recommended approach, since it comes with a number of difficulties when emulating a real GitLab deployment.
The [GDK](https://gitlab.com/gitlab-org/gitlab-development-kit) is not currently set up to run a Prometheus server or `node_exporter` alongside other GitLab components. If you would
like to do so, [Monitoring the GDK with Prometheus](https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/master/doc/howto/prometheus/index.md#monitoring-the-gdk-with-prometheus) is a good start.
The [GCK](https://gitlab.com/gitlab-org/gitlab-compose-kit) has limited support for testing Prometheus based Usage Ping.
By default, it already comes with a fully configured Prometheus service that is set up to scrape a number of components,
but with the following limitations:
- It does not currently run a `gitlab-exporter` instance, so several `process_*` metrics from services such as Gitaly may be missing.
- While it runs a `node_exporter`, `docker-compose` services emulate hosts, meaning that it would normally report itself to not be associated
with any of the other services that are running. That is not how node metrics are reported in a production setup, where `node_exporter`
always runs as a process alongside other GitLab components on any given node. From Usage Ping's perspective none of the node data would therefore
appear to be associated to any of the services running, since they all appear to be running on different hosts. To alleviate this problem, the `node_exporter` in GCK was arbitrarily "assigned" to the `web` service, meaning only for this service `node_*` metrics appears in Usage Ping.
## Aggregated metrics
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/45979) in GitLab 13.6.
> - It's [deployed behind a feature flag](../user/feature_flags.md), disabled by default.
> - It's enabled on GitLab.com.
WARNING:
This feature is intended solely for internal GitLab use.
In order to add data for aggregated metrics into Usage Ping payload you should add corresponding definition in [`aggregated_metrics`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/aggregated_metrics/). Each aggregate definition includes following parts:
- name: unique name under which aggregate metric is added to Usage Ping payload
- operator: operator that defines how aggregated metric data is counted. Available operators are:
- `OR`: removes duplicates and counts all entries that triggered any of listed events
- `AND`: removes duplicates and counts all elements that were observed triggering all of following events
- events: list of events names (from [`known_events/`](#known-events-are-added-automatically-in-usage-data-payload)) to aggregate into metric. All events in this list must have the same `redis_slot` and `aggregation` attributes.
- feature_flag: name of [development feature flag](feature_flags/development.md#development-type) that is checked before
metrics aggregation is performed. Corresponding feature flag should have `default_enabled` attribute set to `false`.
`feature_flag` attribute is **OPTIONAL** and can be omitted, when `feature_flag` is missing no feature flag is checked.
Example aggregated metric entries:
```yaml
- name: product_analytics_test_metrics_union
operator: OR
events: ['i_search_total', 'i_search_advanced', 'i_search_paid']
- name: product_analytics_test_metrics_intersection_with_feautre_flag
operator: AND
events: ['i_search_total', 'i_search_advanced', 'i_search_paid']
feature_flag: example_aggregated_metric
```
Aggregated metrics are added under `aggregated_metrics` key in both `counts_weekly` and `counts_monthly` top level keys in Usage Ping payload.
```ruby
{
:counts_monthly => {
:deployments => 1003,
:successful_deployments => 78,
:failed_deployments => 275,
:packages => 155,
:personal_snippets => 2106,
:project_snippets => 407,
:promoted_issues => 719,
:aggregated_metrics => {
:product_analytics_test_metrics_union => 7,
:product_analytics_test_metrics_intersection_with_feautre_flag => 2
},
:snippets => 2513
}
}
```

## Notable changes
In GitLab 13.5, `pg_system_id` was added to send the [PostgreSQL system identifier](https://www.2ndquadrant.com/en/blog/support-for-postgresqls-system-identifier-in-barman/).
## Exporting Usage Ping SQL queries and definitions
Two Rake tasks exist to export Usage Ping definitions.
- The Rake tasks export the raw SQL queries for `count`, `distinct_count`, `sum`.
- The Rake tasks export the Redis counter class or the line of the Redis block for `redis_usage_data`.
- The Rake tasks calculate the `alt_usage_data` metrics.
In the home directory of your local GitLab installation run the following Rake tasks for the YAML and JSON versions respectively:
```shell
# for YAML export
bin/rake gitlab:usage_data:dump_sql_in_yaml
# for JSON export
bin/rake gitlab:usage_data:dump_sql_in_json
# You may pipe the output into a file
bin/rake gitlab:usage_data:dump_sql_in_yaml > ~/Desktop/usage-metrics-2020-09-02.yaml
```
