OpenTelemetry Java static instrumenter
Structure
Agent instrumenter
Module enhancing OpenTelemetry Java Agent for static instrumentation. The modified agent is capable of instrumenting and saving a new JAR with all relevant instrumentations applied and necessary helper class-code included.
In order to statically instrument a JAR, modified agent needs to be both attached (-javaagent:) and run as the main method (io.opentelemetry.contrib.staticinstrumenter.agent.main.Main class).
:
To instrument you app use opentelemetry-static-agent.jar and pass the main class of the agent:
java -javaagent:opentelemetry-static-agent.jar -cp your-app.jar io.opentelemetry.contrib.staticinstrumenter.agent.main.Main output-folder
To run an instrumented app pass the -Dio.opentelemetry.javaagent.shaded.io.opentelemetry.context.contextStorageProvider=default option and add no-inst-agent.jar to the classpath:
java -Dio.opentelemetry.javaagent.shaded.io.opentelemetry.context.contextStorageProvider=default -cp output-folder/your-app.jar:no-inst-agent.jar org.example.YourMainClass
Gradle plugin
Gradle plugin running static instrumentation agent during the assemble lifecycle task. The assembled archive contains statically instrumened class code.
Maven3 plugin
Maven3 plugin running the static instrumentation agent during the package phase. Packaged archive contains statically instrumened class code.
