Puma exporter

You can use the Puma exporter to measure various Puma metrics.

To enable the Puma exporter:

  1. Enable Prometheus.
  2. Edit /etc/gitlab/gitlab.rb to add (or find and uncomment) the following lines. Make sure puma['exporter_enabled'] is set to true:

    puma['exporter_enabled'] = true
    puma['exporter_address'] = "127.0.0.1"
    puma['exporter_port'] = 8083
    
  3. Save the file and reconfigure GitLab for the changes to take effect.

Prometheus begins collecting performance data from the Puma exporter exposed at localhost:8083.
