Alarm class overrides

To override a class of alarms, disable all alarms within that class. If all alarms within a class for an attribute are disabled, the NMS service interprets the class as having no alarms configured for the attribute and evaluates the next lower class for enabled alarms.

For example, if an alarm is triggered at the Global Custom alarm class level, it means that there are no enabled alarms at the Custom alarms class level for that attribute.

To override a Default alarm, add a Global Custom alarm or Custom alarm for that attribute. This override is achieved because the NMS service does not evaluate lower priority alarm classes once an alarm setting is detected within a class. If this override is performed after an alarm has already been triggered, the override will not take effect until the alarm is triggered again.
