Monitoring Cisco Routers
The eG Enterprise includes special-purpose monitors for Cisco routers to monitor the resource usage and the traffic to and from the Cisco router, so that any sudden increase in load or erosion of resources can be instantly detected, and remedial action immediately initiated.
Using the Cisco Enterprise SNMP MIB, eG agents monitor various metrics of interest relating to Cisco routers. Figure 1 depicts the layer model of a Cisco router.
