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`.
