Splunk Distribution of OpenTelemetry Java

The Splunk Distribution of OpenTelemetry Instrumentation for Java provides a Java Virtual Machine (JVM) agent that automatically instruments your Java application to capture and report distributed traces to Splunk APM.

This distribution comes with the following defaults:

• W3C tracecontext and W3C baggage context propagation; B3 can also be configured.
• OTLP gRPC exporter configured to send spans to a locally running Splunk OpenTelemetry Collector
• Unlimited default limits for configuration options to support full-fidelity traces.

If you're currently using the SignalFx Java Agent and want to migrate to the Splunk Distribution of OpenTelemetry Java, see Migrate from the SignalFx Java Agent.

The following documentation refers to the in-development version of splunk-otel-java. Docs for the latest version (v2.3.0-alpha) can be found here.

Requirements

The agent works with Java runtimes version 8 and higher. For the full list of requirements and supported libraries and versions, see Requirements for the Java agent in the official Splunk documentation.

Correlating traces with logs

The Splunk Distribution of OpenTelemetry Java provides a way to correlate traces with logs. For more information see Connect Java application trace data with logs in the Splunk Observability Cloud user documentation.

Manually instrument a Java application

Documentation on how to manually instrument a Java application is available in the OpenTelemetry official documentation. To learn how to add custom metrics to your application see Manual instrumentation.

To extend the instrumentation with the OpenTelemetry Instrumentation for Java, you have to use a compatible API version.

The Splunk Distribution of OpenTelemetry Java version 2.3.0-alpha is compatible with:

• OpenTelemetry API version 1.37.0
• OpenTelemetry Instrumentation for Java version 2.3.0

Snapshot builds

We publish snapshot builds with every merge to the main branch. Snapshots are primarily intended to test new functionality and are not recommended for production use.

Upgrades
