Chapter 6 Event and Alarm Configuration Parameters
Event (Sub-Type) Configuration Parameters
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:
Network Correlation Parameters
These parameters control the alarm’s behavior in initiating an active correlation-search flow:
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.
select-root-cause-method Used to determine the most fitting alarm
from the set of possible root causes sets.
This set may be a result of a correlation flow
or may represent all alarms in the local
Event Correlator component having a
correlation key that matches one of the
EventData object correlation keys.

set of classes
correlation-filters Used to define a set of filters that will
remove, from the potential set of alarms,
unnecessary root causes. For example,
remove from the list all the root causes that
have a weight lower than the event that
wants to correlate.

post-correlation-
applications
Used to define a set of applications that will
be invoked after the event was correlated.
For example, running affected is such an
application.

Name Description Permitted values
correlate Determines whether the alarm should attempt to
find and correlate to a root-cause alarm. If this
parameter is set to true at least box level
correlation will be performed.
True or false
Name Description Permitted values
activate-flow Determines whether to initiate network level
correlation.
True or false
weight Defines the weight of an alarm as a correlation
candidate. The heavier the alarm, the more
likely it will be chosen as the root cause.
Positive integer
