Java metrics (deprecated) πŸ”—

Caution

This integration is deprecated and will reach End of Support on February 15th, 2025. During this period only critical security and bug fixes are provided. When End of Support is reached, the monitor will be removed and no longer be supported, and you won’t be able to use it to send data to Splunk Observability Cloud.

To forward metrics from a Java application to Splunk Observability Cloud use the Splunk Distribution of OpenTelemetry Java instead. To activate metrics collection in the OpenTelemetry Java agent, see Activate metrics collection.

The Splunk Distribution of the OpenTelemetry Collector uses the Smart Agent receiver with the java-monitor to retrieve metrics from a Java application.

This integration is available on Linux and Windows.

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 the OpenTelemetry Collector to your host or container platform:

  2. Configure the integration, as described in the Configuration section.

  3. Restart the Splunk Distribution of the 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/java-monitor:
    type: java-monitor
    ... # Additional config

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

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

Configuration settings πŸ”—

The following table shows the configuration options for the java-monitor:

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
