When attempting to configure probes on a secondary (remote) hub connected via a hub tunnel, a MONS-002 error occurs similar to the following:
On all hubs:
UIM version: 8.4
The mpse probe should only be installed on the primary hub. Having this probe installed and activated on all hubs in the UIM environment was causing the MONS-002 errors when attempting to configure probes on the remote hubs.
Delete the mpse probe from all hubs except for the primary hub.
