Description Clayton Coleman 2021-01-21 14:44:42 UTC 
Our previous metrics were inadequate for calculating pod request and limits - completed pods were supposed to be excluded, init containers were not included, and overhead wasn't calculated. Starting with 4.7 we now have a Kube metric that calculates this correctly from the scheduler - kube_pod_resource_request and kube_pod_resource_limit - and the console can use them quite easily.

Update the console with the new metrics.

01 - no request line

# oc get pods console-664f87d4f-f99fq  -n openshift-console -o json | jq '.spec.containers[0].resources.requests'
{
  "cpu": "10m",
  "memory": "100Mi"
}

On a cluster with PR fix, CPU/Memory Usage charts doesn't show the request line(orange dotted line), see attachment 01 [details] - no request line.

Assigning back for double confirmation

I see this as well for the console pod. Assigning back to Clayton. Clayton, let us know if you'd like someone on the console team to investigate.

Pod CPU/Memory requests/limits is shown correctly, see attachment 'pod CPU/Memory requests/limits' 
Project CPU/Memory requests is shown correctly, see attachment 'project CPU/Memory requests'
