Hello @maschnetwork
I'm still trying your setup to get some comparisons. I was trying to apply this to one of my apps. Unfortunately I got NoClassDefFoundError: com/amazonaws/services/lambda/runtime/LambdaLogger - apparently it doesn't like my logger setup. It was working properly without the instrumentation, though.
Anyway, I stepped back to the documentation and according to https://docs.aws.amazon.com/lambda/latest/dg/java-logging.html, this is the basic needed setup: https://github.com/awsdocs/aws-lambda-developer-guide/blob/main/sample-apps/java-basic/pom.xml (or here: https://github.com/awsdocs/aws-lambda-developer-guide/blob/main/sample-apps/blank-java/pom.xml) - does it still apply to custom runtimes?
Unfortunately it looks like I still miss some additional setup because with the instrumentation applied and the above setup I get: WARNING: sun.reflect.Reflection.getCallerClass is not supported. This will impact performance.
The app works fine but from the logs I can see it may impact the performance:
