16.3.6 Viewing History
Tip Double-click an alarm in the History window to display the corresponding view. For example,
double-clicking a card alarm takes you to card view. In network view, double-clicking a node alarm takes
you to node view (single-shelf mode) or shelf view (multishelf mode).
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.
16.3.6.1 History Column Descriptions
Table 16-6 lists the History window column headings and the information recorded in each column.
16.3.6.2 Retrieving and Displaying Alarm and Condition History
You can retrieve and view the history of alarms and conditions, including transient conditions (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 (single-shelf mode) or shelf view (multishelf mode), and card history in the card view).
