Description Michael Gugino 2020-09-11 15:03:40 UTC 
More details here: https://issues.redhat.com/browse/OCPCLOUD-842

Current alert timings are arbitrary and have some race conditions with MHC and cluster autoscaler that result in flapping for broken nodes.

Scale up machineset, then delete nodes but machine still exist.
Enable machinehealthcheck
Check Alerting,  alert MachineWithoutValidNode severity is Warning.
