Hi @abelfodil. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

I wonder how relevant the user information is and if we shouldn't just exclude the processOwnerDetector{} detector from the list instead.

Maybe the descheduler itself could detect whether the tracing is enabled and set the USER env from within? E.g. traefik/traefik@a14575d:

os.Setenv("USER", "descheduler")
