Reset health on multiple servers

[mikedisd]

I thought this would be a straight forward and obvious thing to execute but I couldn't find anything that worked from a web search. We had an infrastructure upset that was quickly rectified but it left ~50 servers in a false positive state of Critical . I need a method to perform a Reset Health on all the servers listed as critical.

 

I thought having something like this in a loop would work but it made no difference:

Get-SCOMMonitoringObject { $_.HostComputer.RecalculateMonitoringState() }

 

Any ideas?

One year on, found that putting all unhealthy servers into maintenance mode for 10 minutes sorted them out.
