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.

Yes :) I think that you have to select the pod to get to the timeline :) sorry for not writing that.

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.

I fixed the utilization for containers last week: https://bugzilla.redhat.com/show_bug.cgi?id=1283683
