Umm... perhaps I'm missing something but I don't see how one can determine "exactly how the WAN link is performing" from pinging and tracerouteing.
easy. Congestion, steady state or transient, is shown by the millisecond delay from mtr along the route to each hop.
I'd much prefer looking at the output of a 'show interfaces' on a Cisco router to see what the router thinks is going on. Of particular interest would be reliability, transmit load, receive load, and all the various error counters.
Sure, but not everybody who runs Imail has admin access to the local router or Cisco command skills.
I'd be very surprised if the conclusions about the health of a route from mtr stats and cisco stats would be totally different. I would expect them to be identical, with mtr being much more accessible than cisco commands.
mtr shows packet counts and losses per node, ping round-trip-time as min/avg/max per node. A quick and dirty and easy go/nogo tool.
