 # Monitoring AWS resources **(FREE)**
 
-> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/12621) in GitLab 9.4
-
-GitLab has support for automatically detecting and monitoring AWS resources, starting with the [Elastic Load Balancer](https://aws.amazon.com/elasticloadbalancing/). This is provided by leveraging the official [Cloudwatch exporter](https://github.com/prometheus/cloudwatch_exporter), which translates [Cloudwatch metrics](https://aws.amazon.com/cloudwatch/) into a Prometheus readable form.

 ## Configuring Prometheus to monitor for Cloudwatch metrics
 
-To get started with Cloudwatch monitoring, you should install and configure the [Cloudwatch exporter](https://github.com/prometheus/cloudwatch_exporter) which retrieves and parses the specified Cloudwatch metrics and translates them into a Prometheus monitoring endpoint.

-Right now, the only AWS resource supported is the Elastic Load Balancer, whose Cloudwatch metrics are [documented here](https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/elb-cloudwatch-metrics.html).

 ## Specifying the Environment label
 
-In order to isolate and only display relevant metrics for a given environment
-however, GitLab needs a method to detect which labels are associated. To do this, GitLab [looks for an `environment` label](index.md#identifying-environments).
