RMON2 Overview

RMON2 extends the network traffic monitoring to the higher protocol layers. RMON2 adds insight to those traffic statistics by specifying the protocol and applications that compose that traffic. The traffic knowledge is critical to deploying and troubleshooting today's client/server environments. RMON2 extends the limited RMON1 local segment view to the global network view.

RMON2 is defined in the RFC 2021. (RMON2 MIB)

The LoriotPro RMON plugin is RMON2 compliant and thus can show the network manager who is talking to whom and what application(s) they are using. With this detailed knowledge of the traffic flow in the network and how the traffic from client/server applications is varying, the network administrator can ensure that users and resources are located in the right network, optimize performance and discover network usage.

are group supported by The LoriotPro RMON plugin.

RMON GUI	Group	Description
	Protocol Directory(11)	Lists the inventory of protocols that the probe can monitor
	Protocol Distribution(12)	Collects the number of octets and packets for protocols detected on a network segment
	Network Layer Host(14)	Counts the amount of traffic sent from and to each network address discovered by the probe
	Network Layer Matrix(15)	Counts the amount of traffic sent between each pair of network addresses discovered by the probe
	Application Layer Host(16)	Counts the amount of traffic, by protocol, sent from and to each network address discovered by the probe
	Application Layer Matrix(17)	Counts the amount of traffic, by protocol, sent between each pair of network addresses discovered by the probe
	User History(18)	Periodically samples user-specified variables and logs the data based on user-defined parameters
	Probe Configuration(19)	Defines standard configuration parameters for RMON probes
	Address Map(13)	Lists MAC-address-to-network-address bindings discovered by the probe, and the interface on which the bindings were last seen

The RMON MIB tree branch.

The prefix al is used for Application Layer and the prefix nl is used for Network Layer.
