Grafana Loki

https://github.com/grafana/loki/blob/master/docs/README.md

> Grafana Loki is a set of components that can be composed into a fully featured logging stack.

The plan is not to really use this, just to see what interesting ideas are in there.

[http](https://github.com/influxdata/telegraf/tree/1.11.1/plugins/inputs/http).
Telegraf will save in the `telegraf` database from the embedded influxdb server.
## Grafana
You'll have to add yourself the influxdb data source in grafana, using the
parameters published by the slapos instance.
A default user is created, username and password are published as connection
parameters. You can add more users in grafana interface.
http://docs.grafana.org/features/datasources/influxdb/
When adding datasource, use *proxy* option, otherwise Grafana makes your
browser query influxdb directly, which also uses a self signed certificate.
One workaround is to configure your browser to also accept influxdb certificate
before using grafana, but using proxy seems easier.
Datasources should be automatically added.
## Influxdb
......@@ -34,8 +31,32 @@ One important thing to notice is that the backup protocol is enabled on ipv4
provided by slapos, so make sure this ip is not reachable from untrusted
sources.
## TODO
# Ingesting/Visualizing logs
Eventhough main feature is visualizing metrics, Grafana has a feature called "Explore" to view logs for a time frame.
The following backend can be used:
## Loki
See `TestLoki` in test for an example.
## Influxdb
Influxdb logs only have tags and there does not seem to be a way to search (except than tag and time frame).
To inject log files containing:
```
INFO the message
WARN another message
```
use config like:
```
[[inputs.logparser]]
files = ["/tmp/x*.log", "/tmp/aaa.log"]
* influxdb and telegraf runs with very low priority, this could become an option
* make one partition for each service and use switch software type
* make it easier to add custom configuration (how ?)
[inputs.logparser.grok]

patterns = ['^%{WORD:level:tag} %{GREEDYDATA:message:string}']
