Host metadata properties 🔗

Description 🔗

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

The host-metadata monitor collects metadata properties about a host. This monitor 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 may 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.

Installation 🔗

This monitor is provided by the Smart Agent and is available by using the SignalFx Smart Agent Receiver in the Splunk Distribution of OpenTelemetry Collector.

To install this integration:

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

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

Configuration 🔗

The Splunk Distribution of OpenTelemetry Collector allows embedding a Smart Agent monitor configuration in an associated Smart Agent Receiver instance.

Note: Providing a host-metadata monitor entry in your Smart Agent or Collector configuration is required for its use. Use the appropriate form for your agent type.

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: host-metadata
   ...  # Additional config

See Smart Agent example configuration for an autogenerated example of a YAML configuration file, with default values where applicable.

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/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.

See configuration examples for specific use cases that show how the Splunk 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 that are 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.
