This is a UI bug but the logs attached are the backend ones. Dafna please attach the production.log as well (you should see the stacktrace there).

There should be another step: "select a random pod" between 3 and 4, right Dafna (I was getting the same error in that case).
I have the feeling that this may reproduce with "Utilization" as well (not just "Timeline"). Can you test that as well? Thanks.

Utilization is not working to begin with (just select it and get an error) Will add the log for that but I think it was a bug that was already opened?

thanks Dafna, and it's true one needs to select a specific pod (or other entity in general). Anyway, I'm working on it. (In reply to Dafna Ron from comment #6) > Utilization is not working to begin with (just select it and get an error) I fixed the utilization for containers last week: https://bugzilla.redhat.com/show_bug.cgi?id=1283683
