Cisco Systems 3.6 Correlation Configuration Parameters, Network Correlation Parameters

Chapter 6 Event and Alarm Configuration Parameters

Event (Sub-Type) Configuration Parameters

Name	Description	Permitted Values
select-root-cause-method	Used to determine the most fitting alarm	Select the class name
	from the set of possible root causes sets.	to be used from the
	This set may be a result of a correlation flow	set of classes
	or may represent all alarms in the local
	Event Correlator component having a
	correlation key that matches one of the
	EventData object correlation keys.
correlation-filters	Used to define a set of filters that will	Select the class name
	remove, from the potential set of alarms,	to be used from the
	unnecessary root causes. For example,	set of classes
	remove from the list all the root causes that
	have a weight lower than the event that
	wants to correlate.
post-correlation-	Used to define a set of applications that will	Select the class name
applications	be invoked after the event was correlated.	to be used from the
	For example, running affected is such an	set of classes
	application.

For more information about root cause see Correlation By Root Cause, page 1-5.

Correlation Configuration Parameters

These parameters define the behavior of the alarm in finding its root-cause alarm:

Name	Description	Permitted values
correlate	Determines whether the alarm should attempt to	True or false
	find and correlate to a root-cause alarm. If this
	parameter is set to true at least box level
	correlation will be performed.

Network Correlation Parameters

These parameters control the alarm’s behavior in initiating an active correlation-search flow:

Name	Description	Permitted values
activate-flow	Determines whether to initiate network level	True or false
	correlation.
weight	Defines the weight of an alarm as a correlation	Positive integer
	candidate. The heavier the alarm, the more
	likely it will be chosen as the root cause.

Note All delays should be smaller than the expiration time to allow correlation to take place. Flow activation delay is being counted only when the correlation delay has expired.
