Node Exporter

When running SNClient on Linux or macOS there is a built-in node exporter which can be enabled by:

[/modules]
NodeExporterServer = enabled

[/settings/NodeExporter/server]
; use same port as the web server
port = ${/settings/WEB/server/port}

; disable password protection
require password = false

You can then scrape Linux metrics from http://<ip>:8443/node/metrics.

The node exporter will run as user nobody unless you set agent user otherwise.

The Prometheus scrape config might look like this:

- job_name: 'node'
  # Override the global default and scrape targets from this job every 5 seconds.
  scrape_interval: 5s

  # metrics_path defaults to '/metrics', but here we use the snclient-prefix
  metrics_path: /node/metrics

  # scheme defaults to 'http'.
  scheme: https
  tls_config:
    insecure_skip_verify: true

  static_configs:
  - targets: ['<ip>:8443']

SNClient will monitor the node exporter’s memory usage and restart the exporter if it exceeds the agent max memory limit. The default is 256MB.
