RMON
– Remote Network Monitoring, RFC 1757– Design goals
• offline operation• proactive monitoring• problem detection and reporting• value-added data• multiple managers
6
RMON Components
• 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

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
