2. Time Updated: The last time when the component was monitored for change in performance
value (if the performance of a component exceeded or dropped below the set threshold level).
3. Time Dispatched: The time when the alarm notifications were dispatched. The current performance
value of a component is also displayed.
Initially, the message No records found matching the given filter criteria is
displayed if there are no component records posted in the Alarm History table.

Understanding alarms history
For P9000 Performance Advisor to start monitoring the performance of a component and generate
an alarm, you must configure the required threshold and dispatch settings on the Activate Alarms
screen, and also enable an alarm for that component. For more information on configuring alarms,
see “Configuring notification and monitoring settings” on page 146. After an alarm is configured,
P9000 Performance Advisor monitors the performance of a component from the next data collection
cycle. A new record is displayed on the Alarm History screen with the time of posting appearing
under Time Posted.
IMPORTANT:
P9000 Performance Advisor posts the record only if data collection is in progress for the XP or the
P9000 disk array to which the component belongs.
While configuring an alarm, if you set threshold and dispatch settings but do not enable the alarm
for a component, P9000 Performance Advisor does not monitor that component and generate an
alarm when required. For example, an alarm is enabled (YES displayed under Active) on the first
record, 2:00, and disabled (NO displayed under Active) on the second record, 2:01. Therefore, in
the next data collection cycle, P9000 Performance Advisor posts a record only for 2:00 on the Alarm
History screen. The time of posting the record is displayed under Time Posted. (The Time Updated and
Time Dispatched columns are not updated as this is the first record posted for the metric value, 2:00).
P9000 Performance Advisor monitors the metric value's performance till the time the corresponding
alarm is disabled, or the metric value record is removed.
In every data collection cycle, P9000 Performance Advisor retrieves and compares the current
performance value of a component with the set threshold value. The time when this value was retrieved
and compared is shown under Time Updated. If the current performance value exceeds the set threshold
value, P9000 Performance Advisor does the following:
1. Posts a new record and displays the time of posting under Time Posted
2. Dispatches an alarm notification of type, P9000 Alarm to the intended recipient
3. Displays the time of dispatch under Time Dispatched
4. Monitors the component till its performance value drops below the set threshold value
5. Updates the time of monitoring under Time Updated
