GitLab Prometheus metrics (FREE SELF)

To enable the GitLab Prometheus metrics:

1. Log in to GitLab as a user with administrator access.
2. On the top bar, select Main menu > Admin.
3. On the left sidebar, select Settings > Metrics and profiling.
4. Find the Metrics - Prometheus section, and select Enable GitLab Prometheus metrics endpoint.
5. Restart GitLab for the changes to take effect.

For installations from source 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 Omnibus GitLab and Chart installations. For source installations, these metrics must be enabled manually and collected by a Prometheus server.

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

Connection pool metrics

These metrics record the status of the database connection pools, and the metrics all have these labels:

• class - the Ruby class being recorded.
  • ActiveRecord::Base is the main database connection.
  • Geo::TrackingBase is the connection to the Geo tracking database, if enabled.
• host - the host name used to connect to the database.
• port - the port used to connect to the database.

Redis metrics

These client metrics are meant to complement Redis server metrics. These metrics are broken down per Redis instance. These metrics all have a storage label which indicates the Redis instance. For example, cache or shared_state.

Metric	Type	Since	Description
gitlab_redis_client_exceptions_total	Counter	13.2	Number of Redis client exceptions, broken down by exception class
gitlab_redis_client_requests_total	Counter	13.2	Number of Redis client requests
gitlab_redis_client_requests_duration_seconds	Histogram	13.2	Redis request latency, excluding blocking commands

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 Omnibus GitLab and tmpfs is available, then GitLab configures the metrics directory for you.
