Memory usage πŸ”—

Note

To collect memory utilization metrics only, use the native OTel component Host metrics receiver.

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the Memory monitor type to send memory usage stats for the underlying host.

On Linux hosts, this monitor type relies on the /proc file system. If the underlying host’s /proc file system is mounted somewhere other than /proc, set the path using the top-level configuration procPath, as shown in the following example:

procPath: /proc

This integration is only available on Kubernetes and Linux.

Benefits πŸ”—

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

Installation πŸ”—

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 πŸ”—

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 πŸ”—

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

receivers:
  smartagent/collectd/memory:
    type: collectd/memory
    ... # Additional config

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

service:
  pipelines:
    metrics:
      receivers: [smartagent/memory]

The following metrics are available for this integration:

Notes πŸ”—

  • 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
