Chapter 6 Event and Alarm Configuration Parameters

Event (Sub-Type) Configuration Parameters

Flapping Event Definitions Parameters

If a flapping event application is enabled on an event, then the following parameters control the alarm’s behavior regarding its flapping state:

Name	Description	Permitted values
Flapping	The maximum amount of time in milliseconds between two alarms	Positive integer
interval	which can be considered as a flapping change.
Flapping	After this amount of changes (each change arriving at an interval	Positive integer
threshold	lower then the flapping interval), the event will be considered as
	flapping.
Update	After this interval in milliseconds an update will be sent.	Positive integer
interval
Clear	The amount of time in milliseconds an event has to stay in one state	Positive integer
interval	to be considered as a normal alarm and not in a flapping state.
Update	After this number of flapping alarms, an update will be sent to the	Positive integer
threshold	gateway updating the alarm with the number of events received.

System Correlation Configuration Parameters

These parameters correctly correlate all the events that occur within the specified timeframe.

Name	Description	Permitted values
correlation-delay	Period of time in milliseconds to wait before	Positive integer
	attempting to find and correlate to a root-cause
	parameter (it is system-wide, not configured per
	event).
time-stamp-delay	Used for normalization of the event occurrence	Positive integer
	time. The value in milliseconds is subtracted
	from the event time, to compensate for the time
	difference with the root-cause alarm. It is also
	used for running the network correlation against
	the historic network configuration.
