This plugin calls the linux traceroute command on the given agent IP and returns the number of hops required to find the host or 9999 on failure. You can configure the UDP port to use, and the maximum number of hops to try.
This can be useful to determine whether a given network interface is working if you have two internet connections. By running a traceroute to the gateway IP for each of the internet connections and ensuring that there are very few hops, you can check that both connections are up without plugging into both of them directly.
