Statistics: Maintain basic usage and error statistics for each subnet monitored by the agent.
History: Record periodical statistic samples available from statistics.
Alarm: Allow management console users to set any count or integer for sample intervals and alert thresholds for
RMON agent records.
Event: A list of all events generated by RMON agent.
Alarm depends on the implementation of Event. Statistics and History display some current or history subnet statistics. Alarm
and Event provide a method to monitor any integer data change in the network, and provide some alerts upon abnormal events
(sending Trap or record in logs).
