Node exporter

The node exporter enables you to measure various machine resources such as memory, disk and CPU utilization.

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

To enable the node exporter:

1. Enable Prometheus.

2. Edit /etc/gitlab/gitlab.rb.

3. Add (or find and uncomment) the following line, making sure it’s set to true:

   node_exporter['enable'] = true

4. Save the file, and reconfigure GitLab for the changes to take effect.

Prometheus begins collecting performance data from the node exporter exposed at localhost:9100.
