GitLab has support for automatically detecting and monitoring HAProxy. This is provided by leveraging the [HAProxy Exporter](https://github.com/prometheus/haproxy_exporter), which translates HAProxy statistics into a Prometheus readable form.

## Metrics supported
| Name | Query |
| ---- | ----- |
2019-09-30 21:07:59 +05:30
| Throughput (req/sec) | `sum(rate(haproxy_frontend_http_requests_total{%{environment_filter}}[2m])) by (code)` |
| HTTP Error Rate (%) | `sum(rate(haproxy_frontend_http_requests_total{code="5xx",%{environment_filter}}[2m])) / sum(rate(haproxy_frontend_http_requests_total{%{environment_filter}}[2m]))` |

## Configuring Prometheus to monitor for HAProxy metrics
To get started with NGINX monitoring, you should install and configure the [HAProxy exporter](https://github.com/prometheus/haproxy_exporter) which parses these statistics and translates them into a Prometheus monitoring endpoint.
## 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](index.md#identifying-environments).
