Monitoring the HP Router

The eG Enterprise includes a specialized monitoring model to monitor the HP Routers. By periodically polling the SNMP MIBs of the target HP Router, the eG agents pull out various metrics of interest relating to the HP Routers. Figure 1 depicts the layer model of a HP router.

Figure 1 : The layer model of the HP Router

Every layer of Figure 1 is mapped to a variety of tests which connect to the SNMP MIB of the HP Router to collect critical statistics pertaining to its performance. The metrics reported by these tests enable administrators to answer the following questions:

  • How well the CPU is utilized by the router?
  • What is the maximum percentage of CPU utilized and the average CPU utilization?
  • How well memory is utilized by the router?
  • What is the configured power of the router and the current power of the router?
  • What is the current voltage on each voltage test point of the router?
  • How many tunnels are currently active on the router?
  • How well data/packets are transmitted/received by the router?
  • How many packets are actually dropped during transmission/reception?

Since the Network layer has been dealt with Monitoring Web Servers document, the sections to come will discuss the remaining layers of Figure 1.
