remote monitoring <protocol> (RMON) A {network management} {protocol} that allows network information to be gathered at a single computer. Whereas {SNMP} gathers network data from a single type of {Management Information Base} (MIB), RMON 1 defines nine additional MIBs that provide a much richer set of data about network usage. For RMON to work, network devices, such as {hubs} and {switches}, must be designed to support it. The newest version of RMON, RMON 2, provides data about {traffic} at the {network layer} in addition to the {physical layer}. This allows administrators to analyse traffic by protocol. (2003-09-15)
