Viewing History Alarms

You can view all SNMP alarms, in the Web interface's Alarms History table, that have been
raised (active alarms) as well as cleared (resolved). One of the benefits of this is that you
can view alarms that may have been raised and then cleared on a continuous basis. For
example, such an alarm may be raised due to an Ethernet cable that is not securely
attached to the device's Ethernet port, causing the Ethernet link to be sometimes up and
sometimes down. This alarm would not be listed in the Active Alarms table due to it being
cleared. The Alarms History table displays both the cleared alarm and the alarm for which it
was cleared adjacent to one another, as shown in the figure below for alarms #9 and #10.
To configure the maximum number of alarms that can be displayed in the table, use the
AlarmHistoryTableMaxSize ini file parameter. If the maximum is reached and a new alarm
is added to the table, the oldest alarm is removed from the table to accommodate the new
alarm.
Note:
•
The alarms in the table are deleted upon a device reset.
•
For more information on SNMP alarms, refer to the SNMP Reference Guide
document.
