Remote Monitor (RMON)
Remote Monitoring (RMON) is an Internet Engineering Task Force (IETF) monitoring standard
(RFC 1757) that allows console systems and network monitors to exchange statistical and functional
monitoring data, through RMON-compliant console managers and network probes. RMON provides
network administrators with flexibility to satisfy networking demands through console and network
monitoring probes to obtain fault diagnostics, planning, and performance information.
RMON delivers information in nine unique monitoring element groups that provide specific types of
data, which satisfies common network-monitoring requirements. Some RMON groups are dependent
upon others for support, but each is optional so that it is not necessary for vendors to support all groups
within the management information base (MIB). See Table 4-1 for RMON group functions.
