# How events work

An event specifies whether a trap, a log, or a trap and a log are generated to view alarm activity. After RMON is globally enabled, two default events are generated:

- RisingEvent

- FallingEvent

The default events specify that after an alarm goes out of range, the "firing" of the alarm is tracked in both a trap and a log. For example, after an alarm fires at the rising threshold, the rising event specifies that this information be sent to both a trap and a log. Likewise, after an alarm passes the falling threshold, the falling event specifies that this information be sent to a trap and a log.
