Alarm History
Description
This list displays the following options:ul
•
Time posted (default selection): If this option is selected, the
time stamps of when the records are posted on the Alarm
History screen are displayed. A record for a component is
first posted on the Alarm History screen when the following
conditions are met:
◦
Alarm is enabled on the component.
◦
Performance data collection is in progress.
PA pings the component in the next data collection cycle to
receive its current performance value, and also posts a new
record on the Alarm History screen. PA again posts a new
record for the same component and displays the new time
of posting under Time Posted when one of the following
conditions is met:
◦
The alarm is disabled or there are no I/Os transactions
on the component.
◦
The performance of a component rises or drops below
the set threshold level.
•
Time updated: If this option is selected, the time stamps
when PA last collected the latest performance values for all
the components are displayed.
•
Time dispatched: If this option is selected, the time stamps
when PA dispatched the alarm notifications are displayed.
If a record is showing a blank entry for any of these time
stamps, that particular record is skipped during the filtering
phase. Assuming that the I/Os transactions are not happening
on a particular component, and the alarm is also disabled. In
such a case, the Time Updated displays a blank entry for that
component record. Hence, the record is skipped when you filter
based on Time Updated option.
