Description Clayton Coleman 2019-03-01 19:39:50 UTC
Prometheus operator reports using ~0.15 core continuously, which is more than prometheus.  Since it's doing nothing, it should be more like 0.01 or lower core.  Probably a hot loop or a busy check.

$ oc adm top pod prometheus-operator-7c54f4d9ff-nx7r7 -n openshift-monitoring
NAME                                   CPU(cores)   MEMORY(bytes)   
prometheus-operator-7c54f4d9ff-nx7r7   164m         32Mi        

change back to MODIFIED, will verify it when we get correct images
