if the first sample after this entry becomes valid is greater than or equal to this
threshold and the associated alarmStartupAlarm is equal to risingAlarm(1) or
risingOrFallingAlarm(3). After a rising event is generated, another such event
will not be generated until the sampled value falls below this threshold and
reaches the alarmFallingThreshold.
♦ Falling – When the current sampled value is less than or equal to this
threshold, and the value at the last sampling interval was greater than this
threshold, a single event will be generated. A single event will also be generated
if the first sample after this entry becomes valid is less than or equal to this
threshold and the associated alarmStartupAlarm is equal to fallingAlarm(2) or
risingOrFallingAlarm(3). After a falling event is generated, another such event
will not be generated until the sampled value rises above this threshold and
reaches the alarmRisingThreshold.
♦ Activate Rising/ Falling Event Index – The index of the eventEntry that is
used when a rising threshold is crossed. The eventEntry identified by a
particular value of this index is the same as identified by the same value of the
eventIndex object. If there is no corresponding entry in the eventTable, then no
association exists. In particular, if this value is zero, no associated event will be
generated, as zero is not a valid event index.
♦ Description – A comment describing this event entry.
♦ Community – If an SNMP trap is to be sent, it will be sent to the SNMP
community specified by this octet string.
♦ Type – The type of notification that the probe will make about this event. There
are four types: none, log, snmp-trap, and log-and-trap.
3. Click OK or Cancel, as appropriate.
The Alarm parameters are described below:
♦ Owner – The entity that configured the entry and is therefore using the
resources assigned to it.
♦ Index – An index uniquely identifying an entry in the alarm table. Each such
entry defines a diagnostic sample at a particular interval.
♦ Interval –The interval in seconds over which the data is sampled and compared
with the rising and falling thresholds. When setting this variable, care should be
taken in the case of deltaValue sampling – the interval should be set short
enough that the sampled variable is very unlikely to increase or decrease by
more than 2^31 + 1 during a single sampling interval.
♦ Variable – The object identifier of the particular variable to be sampled.
