# Node exporter **(FREE SELF)**
|
|
|
|
The [node exporter](https://github.com/prometheus/node_exporter) enables you to measure
|
|
various machine resources such as memory, disk and CPU utilization.
|
|
|
|
For installations from source you must install and configure it yourself.
|
|
|
|
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 begins collecting performance data from the node exporter
|
|
exposed at `localhost:9100`.
