RMON

from Wikipedia, the free encyclopedia

RMON (Remote Monitoring) is a standard for collecting statistical data in network-compatible devices, storing them in databases and querying data via access (network management).

  • Standard RMON: basic data (monitoring layers 1 and 2 in the OSI model )
  • RMON2: Network performance data (monitoring of all 7 layers in the OSI model )

RMON is an extension of the Simple Network Management Protocol MIB (Management Information Base). Details were set out by the IETF in RFC 2819 and RFC 2021 .

RMON defines an RMON MIB, which supplements the MIB II and provides the network manager with essential information about the network. The most remarkable thing about RMON is the fact that while it is simply the specification of an MIB, it does not make any changes to the underlying protocol, but it does significantly extend the SNMP functionality.

The RMON standard was originally defined in RFC 1271 and was expanded in RFC 1757 and RFC 2819 . Its purpose is to provide proactive monitoring and diagnostics for distributed LANs.
