Host metadata properties 🔗

Description 🔗

Note: This monitor is deprecated in favor of the host-metrics-receiver monitor. Switch to that receiver as the Smart Agent is deprecated. To learn more, see Host metrics receiver.

The Splunk Distribution of OpenTelemetry Collector provides this integration as the host-metadata monitor by using the SignalFx Smart Agent Receiver.

Use this integration to collect metadata properties about a host.

This integration is required for some views in Splunk Observability Cloud to operate. This monitor accepts endpoints. This monitor does not allow multiple instances.

In containerized environments, host /etc and /proc might not be located directly under the root path. You can specify the path to proc and etc using the top level agent configurations procPath and etcPath, as shown in the following example:

procPath: /proc
etcPath: /etc
monitors:
  - type: host-metadata

Metadata updates occur on a sparse interval of approximately 1m, 1m, 1h, and 1d, and continue repeating once per day. Setting the Interval configuration for this monitor does not affect the sparse interval on which metadata is collected.

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:

Configuration example 🔗

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

receivers:
  smartagent/host-metadata:
    type: host-metadata
    ... # Additional config

To complete the monitor activation, you must also include the smartagent/host-metadata 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/host-metadata]

See configuration examples for specific use cases that show how the Splunk Distribution of OpenTelemetry Collector can integrate and complement existing environments.

Metrics 🔗

The following metrics are available for this integration:

Non-default metrics (version 4.7.0+) 🔗

To emit metrics that are not default, you can add those metrics in the generic monitor-level extraMetrics configuration option. Metrics derived from specific configuration options that do not appear in the above list of metrics do not need to be added to extraMetrics.

To see a list of metrics that will be emitted, you can run agent-status monitors after configuring this monitor in a running agent instance.
