opentelemetry-go-instrumentation VS opentelemetry-java-instrumentation

Go

Not sure that you could in any language. Need runtime reflection to have metadata about the original source code. Java and go both have runtime reflection, so it is possible for those languages and go’s auto-instrumentation implementation of OpenTelemetry uses eBPF for exactly that purpose.

We are actually able to handle the long tail of tracing by leveraging the amazing open source community. For languages like Java we use the automatic instrumentation created by the OpenTelemetry community which is really great and support ton of libraries, you can see a list of supported libraries here: https://github.com/open-telemetry/opentelemetry-java-instrum...

As in Python, it creates spans for every method call and HTTP entry point. It also instruments JDBC calls, but we have a Reactive stack and thus use R2DBC. For the record, a GitHub issue is open for adding support.

Download the latest Java agent ‘JAR’ from the official repo on GitHub and copy the opentelemetry-javaagent-all.jar file to your project.

Java OpenTelemetry MongoDB library for Java applications

Download the latest version of the Java JAR agent, and copy jar agent file in your application code. We have placed the agent under the folder named agents.

OpenTelemetry and Java Flight Recorder (JFR) cover most bases. Use the OpenTelemetry Java agent if you want auto-instrumentation or just the APIs if you want to do your own instrumentation.

Download the latest Java JAR agent.

OpenTelemetry provides three repositories to instrument applications. The opentelemetry-java-instrumentation repo contains the code for auto-instrumentation of Java applications.
