Release note (ui change): job details page now has a
profiler tab for more advanced observability into a job's
execution. Currently, we support collecting a cluster-wide
CPU profile of the job.

Jira Issue: DOC-8123

Hi Aditya Maru When I click on Advanced Debugging tab, I see 2 files listed under Execution Detail Files. I did not click the Profile link or the Request Execution Details button, so I do not expect those 2 files to be there. Is this a bug?

Hey Florence Morris no this is working as expected. In some cases we expect to see files there even when they are not requested. I apologize for adding the release not in the PR, this tab is supposed to be undocumented for the upcoming release and only to be used by developers and support. I don’t think we need to add any documentation here.

Kevin Ngo Is it ok to mark this as “Done, Won’t Do”?

I originally marked this as High because this is surfaced on the Jobs page (not the Advanced Debug) page. It seems similar to Statement bundles and Debug.zip which we document pretty extensively for TSEs as well when troubleshooting with customers. Aditya Maru do we only expect L2 to use this profile tab?

Yes for 23.2 we only expect L2 to recommend to TSE how to use this file. I don’t think this page is as ready as Statement Bundles or debug zips. I think this should be doc’ed as internal runbooks but not user facing until we polish it up and get some mileage on how we plan to use it?
