Yup - that's sort of how DisMan handles things. > But initial creation of the entry is bit different.

Except that this assumes that "no valid at point X" is the same as "not valid at all". If there was a temporary blip at the point when the monitoring entry was created, then the creation request would fail. Even if the OID to be monitored became available again a second later. Don't get me wrong - I can see the thinking behind your approach. But it feels a bit more flexible for the management application to make this sort of decision - create the monitoring entry, watch the status object for two or three polling cycles, then delete the entry if things seem to be consistently failing.
