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/mash-prometheus-node-exporter
# To protect the metrics with HTTP Basic Auth, enable and configure the lines below.
# See: https://doc.traefik.io/traefik/middlewares/http/basicauth/#users
# prometheus_node_exporter_container_labels_metrics_middleware_basic_auth_enabled: true
# prometheus_node_exporter_container_labels_metrics_middleware_basic_auth_users: ''

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