Comment 9 Frederic Branczyk 2019-05-28 11:24:51 UTC
We have three related BZs in total in this area, I'd suggest we fix all of them at once, by introducing a recording rule for memory/cpu that is used universally across the stack, that way we can have consistency:

* https://bugzilla.redhat.com/show_bug.cgi?id=1712912
* https://bugzilla.redhat.com/show_bug.cgi?id=1703414
* https://bugzilla.redhat.com/show_bug.cgi?id=1701856

I'd expect this to be solved in the 4.2 time frame.
