Puma exporter (FREE SELF)

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.

For more information on using Puma with GitLab, see Puma.
