moved to OCP on RHV team

Comment 6 Roy Golan 2020-05-25 13:30:05 UTC

A success criteria here is to see that the frequency of the updates goes to once every few minutes, instead of everyt few seconds. 
A regression tests will be to make sure a machine gets updated if there is indeed something to change. like shutting down the VM and starting it again, which should be reflected as a change.

Verified with: openshift-install-linux-4.5.0-0.nightly-2020-05-26-051016

Verification steps:
1. I had both OCP4.4 cluster (where this is not implemented) and OCP4.5 cluster running alongside each other
2. I ran oc get events --watch on both of them
3. I could see that OCP4.4 cluster generated machine update events every ~ 4 minutes
4. OCP4.5 cluster generated update events only when I delete/created new worker machines
