Statistics (RMON group 1)—Collects Ethernet, Fast Ethernet, and Gigabit Ethernet statistics on an
interface.
History (RMON group 2)—Collects a history group of statistics on Ethernet, Fast Ethernet, and
Gigabit Ethernet interfaces for a specified polling interval.
Alarm (RMON group 3)—Monitors a specific 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 (RMON group 9)—Determines the action to take when an event is triggered by an alarm. The
action can be to generate a log entry or an SNMP trap.
