Automated and Coordinated Collection Fail -Over When Polling Un-Responsive Network Devices

Disclosed in this article is a way to automated and coordinated collection fail-over when polling un-responsive network devices.

With network monitors, on occasion communications are broken for various reasons to the network devices being polled by the monitor. This unresponsiveness from the network devices could be caused by many failures, including the network device being down, a router in the path being down, etc. During this outage important network data could be lost, because either the monitors do not continue to monitor the resource from a fail-over monitor, or they incorrectly pick a fail-over monitor which encounters network performance problems and loses data because it can not contain the current schedule for monitoring. As well the monitor may incorrectly diagnose the end-point as being down and stop monitoring it.

The architecture consists of a central control point for a group of distributed network monitors. Each monitor is assigned some collection of network devices to monitor on a given schedule. If the network monitor is unable to monitor a particular device during any polling period, it will notify the central control point, which will then send a notification to the other defined network monitors. Those monitors will receive the notification and will attempt to poll the device for availability, and will report status to the control point. Using the topo...
