Powertools logging correlation ID for java

[burstingninja]

I’ve been trying to show correlation_id via powertools logs “info… etc. “the way it is displayed in python. But I simply haven’t found a way to do it properly. I have tried following the examples on this repo and also the official documentation. But I haven’t been able to get a clear explanation. Hope someone is able to enlighten me with this one.
My current use case is SQS to
Aws lambda with Java based docker image

Hey @burstingninja,

thanks for opening this discussion. Can you help me understand your code so I can reproduce this better? Can you share some high-level code snippet of how you are trying to display the correlation ID? Which Powertools version are you using?

[phipag]

Log4j2 is broken.

What does this mean?

[burstingninja]

That it does not reflect the logs as per the aws powertools JSON format .
Based on the documentation below
https://docs.powertools.aws.dev/lambda/java/latest/core/logging/

and even after reviewing the repo also referenced there.

These keys don’t show when using
Log4j2, but works fine with logback

Which keys are you referring to? Are you referring to the correlation IDs or the keys such as function_name, function_version, etc.?

[burstingninja]

Just the regular ones. Function name for example

In my tests and our official example, the keys show correctly using log4j2.

Based on this, I suspect that you have an issue with your project's logging configuration or a library whose log4j2 version might conflict.

Since you didn't share your config I can't help you on this specific log4j2 issue but I am happy you were successful with using logback. I will resolve this discussion for now as unanswered. If you believe that there is a bug in log4j2, please open an issue.

Use logback don’t use log4j2
