    Viewing Historical Alarms

    Use this procedure to view the historical alarms table.

    Historical Alarms provides you with a view of all resolved and unresolved alarms. To help you manage this list, PSM allows you to apply filters to narrow down the view to the desired subset.

    PSM builds the historical alarms list from active alarms as they are raised (and when NEs are discovered).

    Additionally, for the BTI7000 Series NEs, PSM reads the Alarm Logs table available on the NE, and supplements the historical alarms list with any alarms that are found in that table but missing from PSM's historical alarms list. The PSM server reads that table during NE discovery, and periodically thereafter to ensure the lists are synchronized. The timestamps for the added alarms are based on the timestamps retrieved from the network element, adjusted for the local PSM server's time zone.

    For the other types of NEs (including the BTI7800 Series NEs), PSM builds the historical alarms list based solely on alarms it sees. Consequently, for those NEs, historical alarms do not contain alarms that were raised and cleared prior to PSM managing the device.

    Note: In some cases, you might see duplicate alarms in the historical alarms table. If you delete and then rediscover a network element, PSM might insert the same alarm into the table as it reprocesses the outstanding alarms for the rediscovered NE.

    To access Historical Alarms:

    1. From the main menu choose View>Alarms > Historical Alarms.

    2. To see the full alarm list, select Perform Query with no filters chosen.

    3. To filter historical alarms, select the desired filtering options from the Filter and Sorting Options dialog. You can order results by a specific field and with a set number of alarms displayed per page specified.
