Re: snmpconf pm issue #23 - policy termination
I agree with the proposed text, but it raises a question.
When a policy is no longer active on an element, is another
policy evaluation done to ensure the proper policy
is in force? This may have been discussed; but I don't recall the
My immediate reaction is to say "no, it happens when it happens,
lets not micromanage this thing". Some cases:
1 A policy goes out of schedule. At this point, since a
"policy evaluation cycle" is taking place, the lower precedence
policy will be enforced.
2 A policy is removed from service (via pmPolicyAdminStatus or
pmPolicyRowStatus). Since these require positive action
by a manager, that manager should be responsible for
the state of the elements governed by that policy.
I'm not sure how this would be done, when it involves
forcing a lower precedence policy evaluation to take place.
Perhaps by temporarily changing the pmPolicyFilterMaxLatency
for a short period of time on a policy the manager thinks
should be in force.
3 The element has changed state in such a way as to no longer
be managed by a given policy. Should this just be caught
on the next policy evaluation?
