Chapter 13 Alarm Monitoring and Management
13.4.7 Viewing History
Note In the Preference dialog General tab, the Maximum History Entries value only applies to the Session
window.
Different views of CTC display the following kinds of history:
• The History > Session window is shown in network view, node view, and card view. It shows alarms
and conditions that occurred during the current user CTC session.
• The History > Node window is only shown in node view. It shows the alarms and conditions that
occurred on the node since CTC software was operated on the node.
• The History > Card window is only shown in card view. It shows the alarms and conditions that
occurred on the card since CTC software was installed on the node.
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.
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.
