Prometheus Node 🔗

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the prometheus/node monitor type to wrap the Prometheus Exporter to export server level and OS level metrics and send them to Splunk Observability Cloud. The Node Exporter measures various server resources such as RAM, disk space, and CPU utilization.

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 the OpenTelemetry Collector to your host or container platform:

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

  3. Restart the Splunk Distribution of the OpenTelemetry Collector.

Configuration 🔗

To use this integration of a Smart Agent monitor with the Collector:

  1. Include the Smart Agent receiver in your configuration file.

  2. Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.

Example 🔗

To activate this integration, add the following to your Collector configuration:

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

Next, add the monitor to the service.pipelines.metrics.receivers section of your configuration file:

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

Configuration settings 🔗

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

Notes 🔗

  • To learn more about the available in Splunk Observability Cloud see Metric types

  • In host-based subscription plans, default metrics are those metrics included in host-based subscriptions in Splunk Observability Cloud, such as host, container, or bundled metrics. Custom metrics are not provided by default and might be subject to charges. See Metric categories for more information.

  • In MTS-based subscription plans, all metrics are custom.

  • To add additional metrics, see how to configure extraMetrics in Add additional metrics
