3505.0. "Alarm clearing and alarm fired procedure" by SUBURB::SMYTHI (Ian Smyth 830-3869) Wed Aug 05 1992 14:22

	Why do alarms not run the alarms fired procedure when the 
result of the last evaluation goes from true to false?

eg,
	I have a rule for evaluating utilization of a decnet circuit. 
When it fires, it creates a line in the notification window saying -

Minor  Rule Fired: xxx_circuit_utilization.....

	It also run the alarm fired procedure to send 
mail/pager/opcom etc.

	When the alarm evaluates clear, it creates a line in the
notification window saying - 

Clear  Rule Fired: xxx_circuit_utilization.....

	But it doesn't run the alarms fired procedure so the 
operators who don't use MCC as their primary interface for receiving 
alarms aren't told that the problem has cleared itself.

3505.1Alarms "Cleared" procedure? RALLYE::MERRIFIELDTue Sep 01 1992 19:1710
	This was functionality that was not understood to be useful.  The
"Rule fired procedure" was implemented in DECmcc V1.0 as the ONLY notification
mechanism available in DECmcc.  Shortly afterwards, "Exception procedures" were
added so that it was possible to alarm on "unreachable" entities.

	If you believe that the ability to exceute a command/script procedure
upon a "rule clear" condition is useful, perhaps it can be considered for
a future release of DECmcc.
