I have 4 SCOM groups as shown below – and these 4 are all sub-groups of “Group – Citrix Public Environment” Health Rollups have been configured using Tao Yang’s “OpsMgr 2012 Self Maintenance”

Every now and then this group “Group – Citrix Public Environment” goes into a “Not Monitored” state. See Fig 1.
I then have to put this group in Maintenance Mode for 5 min then it all shows Green again.See Fig 2.

Could someone please explain?

    • I think this might be related to the fact that I have updated to "UR 9" and the agents for that DMZ is still on "UR 8" I'll let you know tomorrow
    • We get this a lot across several platforms. The flushing of the health cache to force health recalculation is time consuming, likewise is maintenance mode. We also tend to have to schedule the maintenance mode as only the "all contained objects" option will clear the erroneous health state, which subsequently places all the contained servers and production applications into maintenance mode. In one example we have eight management servers and we go through flushing the health cache on each until… Continue reading
