+# Monitoring AWS Resources
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/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.
+
+## Metrics supported
+
+| Name | Query |
+| ---- | ----- |
+| Throughput (req/sec) | sum(aws_elb_request_count_sum{%{environment_filter}}) / 60 |
+| Latency (ms) | avg(aws_elb_latency_average{%{environment_filter}}) * 1000 |
+| HTTP Error Rate (%) | sum(aws_elb_httpcode_backend_5_xx_sum{%{environment_filter}}) / sum(aws_elb_request_count_sum{%{environment_filter}}) |
+
+## Configuring Prometheus to monitor for Cloudwatch metrics
+
+To get started with Cloudwatch monitoring, you should install and configure the [Cloudwatch exporter](https://github.com/hnlq715/nginx-vts-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 can be found [here](http://docs.aws.amazon.com/elasticloadbalancing/latest/classic/elb-cloudwatch-metrics.html).
+
+A sample Cloudwatch Exporter configuration file, configured for basic AWS ELB monitoring, is [available for download](../samples/cloudwatch.yml).
+
+## 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 will [look for an `environment` label](metrics.md#identifying-environments).

+# Monitoring NGINX
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/12621) in GitLab 9.4
+
+GitLab has support for automatically detecting and monitoring NGINX. This is provided by leveraging the [NGINX VTS exporter](https://github.com/hnlq715/nginx-vts-exporter), which translates [VTS statistics](https://github.com/vozlt/nginx-module-vts) into a Prometheus readable form.
+
+## Metrics supported
+
+| Name | Query |
+| ---- | ----- |
+| Throughput (req/sec) | sum(rate(nginx_requests_total{server_zone!="*", server_zone!="_", %{environment_filter}}[2m])) |
+| Latency (ms) | avg(nginx_upstream_response_msecs_avg{%{environment_filter}}) * 1000 |
+| HTTP Error Rate (%) | sum(nginx_responses_total{status_code="5xx", %{environment_filter}}) / sum(nginx_responses_total{server_zone!="*", server_zone!="_", %{environment_filter}}) |
+
+## Configuring Prometheus to monitor for NGINX metrics
+
+To get started with NGINX monitoring, you should first enable the [VTS statistics](https://github.com/vozlt/nginx-module-vts)) module for your NGINX server. This will capture and display statistics in an HTML readable form. Next, you should install and configure the [NGINX VTS exporter](https://github.com/hnlq715/nginx-vts-exporter) which parses these statistics and translates them into a Prometheus monitoring endpoint.
+
+If you are using NGINX as your Kubernetes ingress, there is [upcoming direct support](https://github.com/kubernetes/ingress/pull/423) for enabling Prometheus monitoring in the 0.9.0 release.
+
+## 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 will [look for an `environment` label](metrics.md#identifying-environments).
