Datto reporting:
A Microsoft-Windows-Hyper-V-VMMS-Admin - Hyper-V-VMMS monitor in policy Windows: Role - Hyper-V Server was automatically disabled due to rate limiting.
Hunting this down in the event log (Admin log in Hyper-V-VMMS in Apps&Services logs/Microsoft/Windows) gives me:
The description for Event ID 19510 from source Microsoft-Windows-Hyper-V-VMMS cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:

The locale specific resource for the desired message is not present

And the Event log gives you:
