Viewing Alarms
10.2.6.3 Filtering Conditions
The condition display can be filtered to prevent the appearance of conditions (including alarms) with
certain severities or that occurred between certain dates. You can set the filtering parameters by clicking
the Filter button at the bottom-left of the Conditions window. You can turn the filter on or off by clicking
the Filter tool at the bottom-right of the window. CTC retains your filter activation setting. For example,
if you turn the filter on and then log out, CTC keeps the filter active the next time you log in.
10.2.7 Viewing History
The History window displays historic alarm or condition data for the node or for your login session. You
can chose to display only alarm history, only events, or both by checking check boxes in the
History > Shelf window. You can view network-level alarm and condition history, such as for circuits,
for all the nodes visible in network view. At the node level, you can see all port (facility), card, VC
high-order path, and system-level history entries for that node. For example, protection-switching events
or performance-monitoring threshold crossings appear here. If you double-click a card, you can view all
port, card, and VC high-order path alarm or condition history that directly affects the port.
Note In the Preference dialog General tab, the Maximum History Entries value only applies to the Session
window.
Different views of CTC display different 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 > Shelf 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.
