# Prometheus Node Exporter
|
|
|
|
This playbook can configure [Prometheus Node Exporter](https://github.com/prometheus/node_exporter).
|
|
|
|
|
|
## Configuration
|
|
|
|
To enable this service, add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process:
|
|
|
|
```yaml
|
|
########################################################################
|
|
# #
|
|
# prometheus-node-exporter #
|
|
# #
|
|
########################################################################
|
|
|
|
prometheus_node_exporter_enabled: true
|
|
|
|
# To expose the metrics publicly, enable and configure the lines below:
|
|
# prometheus_node_exporter_hostname: mash.example.com
|
|
# prometheus_node_exporter_path_prefix: /metrics/node-exporter
|
|
|
|
# To protect the metrics with HTTP Basic Auth, enable and configure the lines below:
|
|
# prometheus_node_exporter_basicauth_enabled: true
|
|
# prometheus_node_exporter_basicauth_user: your_username
|
|
# prometheus_node_exporter_basicauth_password: your password
|
|
|
|
########################################################################

|
# /prometheus-node-exporter #
|
|

```
|
|
|
|
Unless you're scraping the Prometheus Node Exporter metrics from a local [Prometheus](prometheus.md) instance, as described in [Integrating with Prometheus Node Exporter](prometheus.md#integrating-with-prometheus-node-exporter), you will probably wish to expose the metrics publicly so that a remote Prometheus instance can fetch them.
|
|
|
|
## Usage
|
|
|
|
After you installed the node exporter, your node stats will be available on `mash.example.com/metrics/node-exporter` with basic auth credentials you configured
|
|
|
|
To integrate Prometheus Node Exporter with a [Prometheus](prometheus.md) instance, see the [Integrating with Prometheus Node Exporter](prometheus.md#integrating-with-prometheus-node-exporter) section of the documentation.
