Monitoring Peplink WAN Router
eG Enterprise offers a special-purpose monitoring model for the Peplink WAN Router to monitor the resource usage and the traffic to and from the target router. Any sudden increase in load or depletion of resources on the router can be instantly detected using the monitored model. This way, the administrators are proactively alerted to the issues and enabled to initiate the remedial actions immediately before the users complain about slowness.
By periodically polling the SNMP MIB of the Peplink WAN Router, eG agents monitor various metrics of interest relating to performance of the target router. Figure 1 depicts the layer model of a Peplink WAN Router.
Every layer in the Figure 1 is mapped to various tests to determine the critical statistics related to the performance of the target router. Using the metrics reported by the tests, administrators can find accurate answers for the following performance queries:
- How well the CPU is utilized by the router?
- How well the memory is utilized by the router?
- What is the current status of each access point connected to the router?
- What is the current state of each VPN profile connected to the router via WAN connection?
- What is the throughtput of VPN profiles?
- What is the current status of each WAN connection to the target router?
- How well the data/packets are transmitted/received through each WAN connection?
- How many packets are actually dropped during transmission/reception?
- How long the router has been up since the last reboot?
Since the tests mapped to the Network Layer are elaborately discussed in Monitoring Cisco Router document, the sections to come will discuss the other layers in detail.
