Java metrics (deprecated) 🔗
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 🔗
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 Splunk 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 Use navigators in Splunk Infrastructure Monitoring.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Search the Metric Finder and Metadata Catalog.
Installation 🔗
Follow these steps to deploy this integration:
Deploy the Splunk Distribution of the OpenTelemetry Collector to your host or container platform:
Configure the integration, as described in the Configuration section.
Restart the Splunk Distribution of the OpenTelemetry Collector.
Configuration 🔗
To use this integration of a Smart Agent monitor with the Collector:
Include the Smart Agent receiver in your configuration file.
Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.
See how to Use Smart Agent monitors with the Collector.
See how to set up the Smart Agent receiver.
For a list of common configuration options, refer to Common configuration settings for monitors.
Learn more about the Collector at Get started: Understand and use the Collector.
Example 🔗
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]

Notes 🔗
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.
