3.6.2 Viewing Alarm History
The History tab displays historical alarm data. The History tab also shows the events (that is, non-reported activities) that occur in addition to the alarms. For example, protection switching events or performance monitoring threshold crossings appear here. The History tab presents two alarm history views:
•The Session subtab (Figure 3-15)presents alarms and events for the current CTC session. When you log off, the alarms disappear.
•The Node subtab (Figure 3-16)shows the alarms, events and conditions that occurred at the node since the CTC software installation or last node power up, whichever occurred most recently. The ONS 15327 can store up to 640 critical alarms, 640 major alarms, 640 minor alarms, and 640 events. When the limit is reached, the ONS 15327 discards the oldest alarms and events. To display a stored alarm or event, check the desired boxes and click the Retrieve button.
Tip Double-click an alarm in the alarm 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.
