Auto instrumentation for spring batch jobs and tasks

[ghost]

As per the release notes, auto instrumentation is supported for spring batch 3+ but we cannot see any traces related to jobs and tasklets.
Tried adding the dependency in gradle build file as below
implementation 'io.opentelemetry.javaagent.instrumentation:opentelemetry-javaagent-spring-batch-3.0:0.16.0'

Please suggest if something else needs to be done.

Thanks

Transferring this over to the instrumentation project....

Hi @Nisha-sahu,

The spring batch instrumentation is still turned off by default because of a lack of semantic conventions for batch jobs (they're still under discussion), it's treated as an "experimental" instrumentation.

You can enable it by passing -Dotel.instrumentation.spring-batch.enabled=true in the command line. There's no need to include any dependency in gradle.

Hi, @mateuszrzeszutek! I've been trying to get a sample project to work with the OTEL agent but haven't been successful even though I've added the suggested system property.
I'm running this project: https://github.com/spring-guides/gs-batch-processing
And have added quite a lot of system properties:

-Dotel.javaagent.debug=true
-Dotel.instrumentation.spring-batch.enabled=true
-Dotel.instrumentation.spring-batch.item.enabled=true
-Dotel.instrumentation.spring-batch.experimental.chunk.new-trace=true
-Dotel.instrumentation.spring-batch.experimental-span-attributes=true

I noticed, looking at the code, that unless I'm mistaken the module is always disabled?

Would appreciate any help getting this to work.

Thanks!
