| Description | This object specifies the method used to prevent an excess of
notifications from being generated when operation fluctuates
around a threshold level.
The value 'holdDownTimer' indicates that notifications for a
given threshold and interface are suppressed for a short amount
of time after each notification. The time value is specified
in cifthTemplateNotifyHoldDownTime, which is instantiated only
when this object is set to 'holdDownTimer'. After a
notification is received for a given threshold and interface,
the next notification for that threshold and interface will be
generated after at least cifthTemplateNotifyHoldDownTime amount
of time has passed, only when the threshold is next fired or
cleared.
The value 'fireAndClearThresholds' indicates that hysteresis
is used. The management client configures two values for each
threshold: one for asserting that the threshold has been
exceeded (see cifthThresholdFiredValue), and a second value for
asserting that the threshold is no longer being exceeded (see
cifthThresholdClearedValue, which is instantiated only when
this object is set to 'fireAndClearThresholds').
When this entry in cifthTemplateTable is active, this object
may only be modified if there are no active entries in
cifthThresholdTable with the same value of cifthTemplateIndex. |
