5860.0. "ALARMS don't generate Cleared alarms" by STKHLM::BERGGREN (Nils Berggren EIS/Project dpmt, Sweden DTN 876-8287) Fri Feb 04 1994 07:06

Hi,

Just a simple question,

In the Alarms and Notification Services Use manual in the chapter
"Viewing alarms that have fired" (page 5-18) it says that

 "alarms automatically clears when the condition detected is corrected
  and an event of cleared severity is generated"

Is this true for CHANGE_OF-rules?

I have a rule with the following expression:

CHANGE_OF (Domain SE_NS:.telia.c.nmsystem Rule trigger 
	   state, enabled, disabled),
	   at  every=0:1:0

When I disable the rule trigger, I get the alarm, but when enabling the rule
I don't get any CLEAR-alarm.

I can get the cleared alarm using a comparison-rule.

    Have I missed something?

Well, if you think about it, what clears a change of condition?  Certainly not
another change.  Other conditions that can have true/false rules can have clears,
but a change of rule is neither true or false, just different.  No way to signal a clear.
