56 CHAPTER 7: STATUS MONITORING AND STATISTICS
Statistics
The Statistics group provides traffic and error statistics showing packets,
bytes, broadcasts, multicasts and errors on a LAN segment or VLAN.
Information from the Statistics group is used to detect changes in traffic
and error patterns in critical areas of your network.
History
The History group provides historical views of network performance by
taking periodic samples of the counters supplied by the Statistics group.
The group is useful for analyzing the traffic patterns and trends on a LAN
segment or VLAN, and for establishing the normal operating parameters
of your network.
Alarms
The Alarms group provides a mechanism for setting thresholds and
sampling intervals to generate events on any RMON variable.
Alarms are used to inform you of network performance problems and
they can trigger automated responses through the Events group.
Events
The Events group provides you with the ability to create entries in an
event log and send SNMP traps to the management workstation. Events
are the action that can result from an RMON alarm. In addition to the
standard five traps required by SNMP (link up, link down, warm start, cold
start, and authentication failure), RMON adds two more: rising threshold
and falling threshold.
Effective use of the Events group saves you time; rather than having to
watch real-time graphs for important occurrences, you can depend on
the Event group for notification. Through the SNMP traps, events can
trigger other actions, therefore providing a way to automatically respond
to certain occurrences.
