# Node exporter

>**Note:**
Available since Omnibus GitLab 8.16. For installations from source you'll
have to install and configure it yourself.

The [node exporter](https://github.com/prometheus/node_exporter) allows you to measure
various machine resources such as memory, disk and CPU utilization.

To enable the node exporter:

1. [Enable Prometheus](index.md#configuring-prometheus)
1. Edit `/etc/gitlab/gitlab.rb`
1. Add or find and uncomment the following line, making sure it's set to `true`:

   ```ruby
   node_exporter['enable'] = true
   ```

1. Save the file and [reconfigure GitLab](../../restart_gitlab.md#omnibus-gitlab-reconfigure)
   for the changes to take effect

Prometheus will now automatically begin collecting performance data from
the node exporter exposed under `localhost:9100`.
