23.3.5.3 Filtering Conditions
The condition display can be filtered to prevent display 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 your user ID is
activated.
23.3.6 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 >
Node window. You can view network-level alarm and condition history, such as for circuits, at that level.
At the node level, you can see all port (facility), card, STS, and system-level history entries. 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 STS alarm or condition history that directly affects
the card. See the
“DLP-G116 View Alarm or Event History” task on page 8-8
The ONS 15454 can store up to 640 critical alarm messages, 640 major alarm messages, 640 minor alarm
messages, and 640 condition messages. When any of these limits is reached, the ONS 15454 discards
the oldest events in that category.

In the Preference dialog General tab, the Maximum History Entries value only applies to the Session
window.
