Viewing ONS 15327 Alarms
10.2.4 Viewing History
The
History
tab displays historical alarm data. It also displays events, which are nonalarmed activities
such as timing changes and threshold crossings. For example, protection switching events or
performance monitoring threshold crossings appear here. The History tab presents two alarm history
views:
•
The Session subtab (
) presents alarms and events that have occurred during the current
CTC session.
•
The Node subtab shows the alarms and events that occurred at the node since the CTC software
installation. The ONS 15327 can store up to 640 critical alarms, 640 major alarms, 640 minor
alarms, and 256 events. When the limit is reached, the ONS 15327 discards the oldest alarms and
events.
Tip
Double-click an alarm in the alarm table or an event in the history table 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.
