Openshift [v4.8 ] + Prometheus; openshift cluster operator getting degraded state

Hello all,

Looking for help!

  • Deployed the Prometheus exporter [dellhw /node exporter] for monitoring the all OCP nodes.

  • After the deployment, Performance openshift components become degraded such as kube-apiserver ,openshift-apiserver ,kube-scheduler,service-ca etc.

  • we have env. having 3 master[16 vcp - 96 GB RAM]+306 worker node [4 VCPU -8GB RAM]

  • Request you please help us to understand, how much RAM and CPU can be expected openshift [master?/worker ?] so that we make the openshift infrastructure become stable.
