GitLab Prometheus metrics

DETAILS: Tier: Free, Premium, Ultimate Offering: Self-managed

To enable the GitLab Prometheus metrics:

Log in to GitLab as a user with administrator access.
On the left sidebar, at the bottom, select Admin Area.
Select Settings > Metrics and profiling.
Find the Metrics - Prometheus section, and select Enable GitLab Prometheus metrics endpoint.
Restart GitLab for the changes to take effect.

For self-compiled installations, you must configure it yourself.

Collecting the metrics

GitLab monitors its own internal service metrics, and makes them available at the /-/metrics endpoint. Unlike other Prometheus exporters, to access the metrics, the client IP address must be explicitly allowed.

These metrics are enabled and collected for Linux package and Helm chart installations. For self-compiled installations, these metrics must be enabled manually and collected by a Prometheus server.

For enabling and viewing metrics from Sidekiq nodes, see Sidekiq metrics.

Metrics shared directory

The GitLab Prometheus client requires a directory to store metrics data shared between multi-process services. Those files are shared among all instances running under Puma server. The directory must be accessible to all running Puma's processes, or metrics can't function correctly.

This directory's location is configured using environment variable prometheus_multiproc_dir. For best performance, create this directory in tmpfs.

If GitLab is installed using the Linux package and tmpfs is available, then GitLab configures the metrics directory for you.
