RMON
– Remote Network Monitoring, RFC 1757
– Design goals
• offline operation
• proactive monitoring
• problem detection and reporting
• value-added data
• multiple managers

LAN
• RMON Probe
• Data gatherer - a physical device
• Data analyzer
• Processor that analyzes data
• RMON Remote Network Monitoring
• Standards-based network management protocol
• Allows network information to be gathered at a single workstation
• Defines additional MIBs to provide a richer set of data about network usage
6
RMON Benefits
• Monitors and analyzes locally and relays data;
less load on the network
• Needs no direct visibility by NMS; more reliable
information
• Permits monitoring on a more frequent basis and
hence faster fault diagnosis
• Increases productivity for administrators

RMON Groups and Functions
• Probe gathers data
• Functions
• Statistics on Ethernet, token ring, and
hosts / conversations
• Filter group filters data prior to capture
of data
• Generation of alarms and events

RMON2
• Applicable to Layers 3 and above
• Functions similar to RMON1
• Enhancement to RMON1
• Defined conformance and compliance
