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:
System Correlation Configuration Parameters
These parameters correctly correlate all the events that occur within the specified timeframe.
Name Description Permitted values
Flapping
interval
The maximum amount of time in milliseconds between two alarms
which can be considered as a flapping change.
Positive integer
Flapping
threshold
After this amount of changes (each change arriving at an interval
lower then the flapping interval), the event will be considered as
flapping.
Positive integer
Update
interval
After this interval in milliseconds an update will be sent. Positive integer
Clear
interval
The amount of time in milliseconds an event has to stay in one state
to be considered as a normal alarm and not in a flapping state.
Positive integer
Update
threshold
After this number of flapping alarms, an update will be sent to the
gateway updating the alarm with the number of events received.
Positive integer
Name Description Permitted values
correlation-delay Period of time in milliseconds to wait before
attempting to find and correlate to a root-cause
parameter (it is system-wide, not configured per
event).
Positive integer
time-stamp-delay Used for normalization of the event occurrence
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.
Positive integer
