Node Exporter

When running SNClient+ on linux or osx there is a builtin 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
password =

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 memory usage and restart the exporter if it exceeds the agent max memory. The default is 256MB.
