The RMON Alarm screen contains fields for setting network alarms. Network alarms occur when a network
problem, or event, is detected. Rising and falling thresholds generate events.
The RMON Alarms screen allows you to record important events and critical network problems. The RMON Alarm
and Event Control Tables are used together to define specific criteria that will generate response events.
Alarms can be set to test data over any specified time interval and can monitor absolute or changing values, such
as a statistical counter reaching a specific value, or a statistic changing by a certain amount over a set interval.
Alarms can be set to respond to either rising or falling thresholds.
