Alarm—Monitors a specific management information base (MIB) object for a specified interval,
triggers an alarm at a specified value (rising threshold), and resets the alarm at another value (falling
threshold). Alarms can be used with events; the alarm triggers an event, which can generate a log
entry or an SNMP trap.
Event—Determines the action to take when an event is triggered by an alarm. The action can be to
generate a log entry, an SNMP trap, or both.
