Chapter 10 Alarm Monitoring and Management
Viewing Alarms
If you check the History window Alarms check box, you display the node history of alarms. If you check
the Events check box, you display the node history of Not Alarmed and transient events (conditions). If
you check both check boxes, you retrieve node history for both.
10.2.7.1 History Column Descriptions
Table 10-7 lists the History window column headings and the information recorded in each column.
10.2.7.2 Retrieving and Displaying Alarm and Condition History
You can retrieve and view the history of alarms and conditions, as well as transients (passing
notifications of processes as they occur) in the CTC history window. The information in this window is
specific to the view where it is shown (that is, network history in the network view, node history in the
node view, and card history in the card view).
The node and card history views are each divided into two tabs. In node view, when you click the
Retrieve button, you can see the history of alarms, conditions, and transients that have occurred on the
node in the History > Shelf window, and the history of alarms, conditions, and transients that have
occurred on the node during your login session in the History > Session window. In the card-view history
window, after you retrieve the card history, you can see the history of alarms, conditions, and transients
