How to expose exemplar metrics with auto-instrument

[mvkrishna86]

Hi,
May I know how can I auto-instrument the java code for exposing metrics along with exemplars?
I tried the procedure mentioned here: https://github.com/prometheus/client_java/blob/master/OTEL_EXEMPLARS.md. But in the code, it looks like we have to create the metrics and add the instrumentation before every call.

It is mentioned here: https://github.com/prometheus/client_java/blob/master/OTEL_EXEMPLARS.md, that we can add the exemplars without changing the code. But May I know how to do that?

I'd definitively like to have guidance on this subject too. I also opened the following #4616

I think this is a discussion for the instrumentation repository, rather than the SDK, correct? Assuming you want to configure the javaagent for this, rather than manually configuring the SDK, that is.

[irizzant]

we need to configure the Java auto instrumentation via Java agent to expose Exemplars via Prometheus exporter, but we lack documentation for this

[jkwatson]

right. So, the issue you created over in the instrumentation repo is the right place for this to be discussed, rather than here.

[irizzant]

right, but I found this discussion already here with the very same subject and I just replied to it so I guess it should have been moved before eventually

I'm going to move this over to the instrumentation repo. :)
