Description of problem:
the bug is found when debug https://issues.redhat.com/browse/OCPQE-13200
deploy 4.8.0-0.nightly-2022-11-30-073158 with aos-4_8/ipi-on-aws/versioned-installer-ovn-winc-ci template, the template created cluster with 3 linux masters, 3 linux workers and 2 windows workers. ip-10-0-149-219.us-east-2.compute.internal/ip-10-0-158-129.us-east-2.compute.internal are windows workers in this bug(they are with kubernetes.io/os=windows label, not kubernetes.io/os=linux).

reason why CMO reports monitoring is degraded is 4.8 treats all Ready node to nodeReadyCount, no matter they have kubernetes.io/os=linux or not
the issue is fixed in 4.9+
Version-Release number of selected component (if applicable):
deploy 4.8.0-0.nightly-2022-11-30-073158 with aos-4_8/ipi-on-aws/versioned-installer-ovn-winc-ci template, the template created cluster with 3 linux masters, 3 linux workers and 2 windows workers
How reproducible:
deploy OCP 4.8 on linux worker + windows worker
Steps to Reproduce:
1. see the description 2. 3.
Actual results:
monitoring is degraded for waiting for DaemonSetRollout of openshift-monitoring/node-exporter: expected 8 ready pods for "node-exporter" daemonset, got 6
Expected results:
no degraded
Additional info:
if we don't want to fix the bug in 4.8, we can close this bug
