Prometheus Node Exporter 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the prometheus/node monitor type using the Smart Agent Receiver.

Use this integration to collect Prometheus Node Exporter metrics and send them to Splunk Observability Cloud. This monitor is a wrapper around the Prometheus Exporter monitor.

This integration is available for Kubernetes, Linux, and Windows.

Benefits 🔗

After you configure the integration, you can access these features:

Installation 🔗

Follow these steps to deploy this integration:

  1. Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:

  2. Configure the monitor, as described in the Configuration section.

  3. Restart the Splunk Distribution of OpenTelemetry Collector.

Configuration 🔗

This monitor type is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector. You can use existing Smart Agent monitors as OpenTelemetry Collector metric receivers with the Smart Agent Receiver.

This monitor type requires a properly configured environment on your system in which you’ve installed a functional Smart Agent release bundle. The Collector provides this bundle in the installation paths for x86_64/amd64.

To activate this monitor type in the Collector, add the following lines to your configuration (YAML) file:

Note

Provide a prometheus/node monitor entry in your Smart Agent or Collector configuration. Use the appropriate form for your agent type.

Splunk Distribution of OpenTelemetry Collector 🔗

To activate this monitor in the Splunk Distribution of OpenTelemetry Collector, add the following to your agent configuration:

receivers:
  smartagent/prometheus-node:
    type: prometheus/node
    ...  # Additional config

To complete the monitor activation, you must also include the smartagent/prometheus-node receiver item in a metrics pipeline. To do this, add the receiver item to the service > pipelines > metrics > receivers section of your configuration file. For example:

service:
  pipelines:
    metrics:
      receivers: [smartagent/prometheus-node]

Smart Agent 🔗

To activate this monitor in the Smart Agent, add the following to your agent configuration:

monitors:  # All monitor config goes under this key
  - type: prometheus/node
    ...  # Additional config

See Install and configure the SignalFx Smart Agent for an autogenerated example of a YAML configuration file, with default values where applicable.

Configuration settings 🔗

The following table shows the configuration options for the prometheus/node monitor:
