Java metrics receiver πŸ”—

Description πŸ”—

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

Use the Java receiver to retrieve metrics from a Java application.

This receiver is available on Linux and Windows.

Note

To enable metrics collection in the OpenTelemetry Java agent, see Enable metrics collection.

Benefits πŸ”—

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

  • View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. 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 the Metric Finder and search for metrics sent by the monitor. For information, see Use the Metric Finder.

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”—

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:

receivers:
  smartagent/java-monitor:
    type: java-monitor
    ... # Additional config

To complete the receiver activation, you must also include the receiver in a metrics pipeline. To do this, add the receiver to the service > pipelines > metrics > receivers section of your configuration file. For example:

service:
  pipelines:
    metrics:
      receivers: [java-monitor]
