RMON Statistics Configuration
RMON is short of Remote Monitoring On Network. An RMON implementation
typically operates in a client/server model. Monitoring device (Probe) contains
RMON software agents that collect information of the system and ports. The RMON
software agent acts as server, and the network management system (NMS) that
communicate with it acts as client. The RMON agent of the switch supports 4 groups,
such as the Statistics, History, Alarm and Event.
RMON Group Function Elements
Statistics Contains statistics measured
by the probe for each
monitored interface on this
device.
Real-time LAN statistics e.g.
utilization, collisions, CRC errors
Packets dropped, packets sent, bytes
sent (octets), broadcast packets,
multicast packets, CRC errors, undersize
packets, oversize packets, fragments,
jabbers, collisions, and counters for
packets ranging from 64, 65 to 127, 128
to 255, 256 to 511, 512 to 1023, and 1024
to 1518 bytes.
History Records periodic statistical
samples from a network and
stores for retrieval. History of above Statistics.
Alarm Definitions for RMON SNMP
traps to be sent when statistics
exceed defined thresholds Interval for sampling, particular variable,
sample type, value of statistics during the
last sampling period, startup alarm, rising
threshold, rising index, falling threshold,
falling index.
Events Controls the generation and
notification of events from this
device. Event index, log index, event log time,
