Introduction
All N-Squared applications running under the N2SVCD framework generate:
- Events (WARNING or NOTICE) related to a single “event”,
- Alarms (ALARM or CLEAR) which flag an ongoing alarm state, and/or
- Statistics that count the occurrences of various occasions.
Events, alarms, and statistics are generated automatically as part of a running installation. For more information about the configuration and operational management of such messages, refer to the N2SVCD technical guide sections on alarm documentation or statistics configuration respectively.
Actual alarm and statistic content and details are available:
- for all applications' alarms or statistics, or
- individually for each application and its components, as shown in the sections on the left.
