Java

A language-specific implementation of OpenTelemetry in Java.

OpenTelemetry Java consists of the following repositories:

• opentelemetry-java: Components for manual instrumentation including API and SDK as well as extensions, the OpenTracing shim and examples.
• opentelemetry-java-instrumentation: Built on top of opentelemetry-java and provides a Java agent JAR that can be attached to any Java 8+ application and dynamically injects bytecode to capture telemetry from a number of popular libraries and frameworks.
• opentelemetry-java-contrib: Provides helpful libraries and standalone OpenTelemetry-based utilities that don’t fit the express scope of the OpenTelemetry Java or Java Instrumentation projects. For example, JMX metric gathering.
