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 locally installed [Prometheus](prometheus.md) service, see the [Integrating with Prometheus Node Exporter](prometheus.md#integrating-with-prometheus-node-exporter) section of the documentation.
