However, this service is very important for the SCOM R2 Management Group as a whole. So it is better to override this Monitor (Enabled > True) in order to enable it. And don’t forget to store this override in a MP of its own.
I have read the guide related to this MP but I haven’t found anything why this has been done.
Another thing one can choose for is to enable a Recovery action for this monitor. By default it is not enabled. Open the Overrides tab for this Monitor, select the option Recovery > Start Management Configuration Service. Click the button Overrides > For all objects of Class: Root Management Server > and set Enabled to True, don’t forget to store this override in a MP of its own.
