Host process list 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the processlist monitor type by using the SignalFx Smart Agent Receiver.

This monitor reports the running processes for a host, analogous to how the top or ps command on Unix/Linux systems works. The output format is a special base64-encoded event that gets processed by our backend and displayed under the Infrastructure view for a specific host. Historical process information is not retained on the backend, only the most recent version.

This monitor is available on Linux and Windows.

Benefits 🔗

After you’ve configured the integration, you can:

  • View metrics using the built-in dashboard. For information about dashboards, see View dashboards in Observability Cloud.

  • View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Splunk Infrastructure Monitoring navigators.

  • Access Metric Finder and search for metrics sent by the monitor. For information about Metric Finder, see Use the Metric Finder.

Installation 🔗

Follow these steps to deploy the 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.

  3. Restart the Splunk Distribution of OpenTelemetry Collector.

Configuration 🔗

This monitor is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector. The Smart Agent Receiver lets you use existing Smart Agent monitors as OpenTelemetry Collector metric receivers.

Using this monitor assumes that you have a configured environment with a functional Smart Agent release bundle on your system, which is already provided for x86_64/amd64 Splunk Distribution of OpenTelemetry Collector installation paths.

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

receivers:
  smartagent/processlist:
    type: processlist
    ...  # Additional config

To complete the monitor activation, include this monitor in a logs pipeline with the following options:

  • signalfx exporter. The signalfx exporter can be used to send metrics, events, and trace correlation to Infrastructure Monitoring.

  • resourcedetection processor. The resourcedetection processor can be used to detect resource information from the host, in a format that conforms to the OpenTelemetry resource semantic conventions, and append or override the resource value in telemetry data with this information.

For example:

service:
  pipelines:
    logs:
      receivers: [smartagent/processlist]
      exporters: [signalfx]
      processors: [resourcedetection]

Metrics 🔗

The Splunk Distribution of OpenTelemetry Collector does not do any built-in filtering of metrics for this monitor.
