Hi

I have a SCOM 2012 R2 installation. All my 440 agents (except 4) have changed status to 'Not Monitored'.  I have tried uninstalling the agents as well as flushing the 'Health Service State and Cache' on several with no improvements. 

Also the 'Management Server State' console also reports the Health Service Watch view as both management servers listed as 'Healthy' but the 'Management Server State' shows 'Not monitored'.

Where do you advise I start looking to remediate?

Hi

I'd suggest a support call so that someone can find a resolution quickly as monitoring is completely down. Forums are great for providing ideas to solve problems but if you need a quick response \ recovery then support is really the best bet.

If you want to do this through the forums then I'd suggest:

1. Check the OperationsManager event logs on the management servers for any errors \ warnings.

2. Although nothing appears to be in maintenance mode, I'd run this:

Get-SCOMMaintenanceMode

3. This is at your own risk but have you Flushed the Health Service State Cache on the Management Servers?

Cheers

Recommend troubleshoot steps
1) check event log
2) flush 'Health Service State and Cache'  for both Management server and agent
3)  restarting the System Center Management Health service
4) check the DNS configuration for the computer, both FQDN and DNS suffix
5) check whether the appropriate management pack for monitoring the object is imported
6) Ensure that the appropriate monitors are enabled
7) try placing the object in maintenance mode for several minutes
