Description Clayton Coleman 2019-08-12 18:49:59 UTC

+++ This bug was initially created as a clone of Bug #1740372 +++

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.

--- Additional comment from Clayton Coleman on 2019-08-12 14:49:12 EDT ---

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.
