Description Clayton Coleman 2019-08-12 18:48:20 UTC 
infrastructure CPU calculations don't take into account the processes running on the nodes.

Instead of the current calculation, find all workload CPU/memory usage not in the openshift-* namespaces, then subtract that from the cluster CPU usage to get infrastructure use.
Comment 1 Clayton Coleman 2019-08-12 18:49:12 UTC 
Metrics 

workload:cpu_usage_cores:sum
workload:memory_usage_bytes:sum

are added

openshift:cpu_usage_cores:sum
openshift:memory_usage_bytes:sum

now include all CPU/memory on nodes not explicitly part of a workload.
