4.12 View Alarm and Event History

All historical alarms and events are displayed in a scrollable, optionally filterable table. The historical alarms and events are sorted, by default, by time stamp with the most recent one at the top. Use this procedure to view alarm and event history.

Note:

The alarms and events that appear in View History vary depending on whether you are logged in to an NOAM or SOAM. Alarm collection is handled solely by NOAM servers in systems that do not support SOAMs.

1. Click Alarms & Events, and then View History.
2. If necessary, specify filter criteria and click Go.

   Note:

   Some fields, such as Additional Info, truncate data to a limited number of characters. When this happens, a More link appears. Click More to view a report that displays all relevant data.
   Historical alarms and events are displayed according to the specified criteria.

   The historical alarms table updates automatically. When new historical data is available, the table is automatically updated, and the view returns to the top row of the table.

3. To suspend automatic updates, click any row in the table.
   The following message appears: (Alarm updates are suspended.)

   If a new alarm is generated while automatic updates are suspended, a new message appears: (Alarm updates are suspended. Available updates pending.)

   To resume automatic updates, press and hold Ctrl as you click to deselect the selected row.
