Monitoring Cisco ASR Routers
The eG Enterprise monitors the resource usage and the traffic to and from the Cisco ASR 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 ASR routers.Figure 1 depicts the layer model of Cisco ASR Router.
Every layer in the monitoring model is mapped to variety of tests which connect to the SNMP MIB of the target router and report critical statistics pertaining to its performance. Using the measures reported by the tests administrators can find quick and accurate answers for the following queries:
- Is the Flash file in ASR Router is valid?
- Is the type of the Flash file in ASR Router is unknown?
- Is the Admin status of the Field Replaceable Units (FRU) in ASR router is in off state?
- Is the Operational status of the Field Replaceable Units (FRU) in ASR router is in on state?
- Is the stored message queues in the target router are very low in number?
- Is the number of discarded message queues in the target router is high?
- How well the buffer and cache pools are utilized by ASR Router?
- How efficient the FTP Client Requests are handled in ASR Router?
- Is the average CPU time taken by the processor is too high?
- How well the memory is utilized from the memory pool?
