The best tool I've found for monitoring connections, routes, congestion,
is called PingPlotter.  http://pingplotter.com/   It's a shareware 
visual traceroute.  It continually graphs the traceroute style
responses.  There is a scrollable timeline to view how things change.
You can get raw data out of it as well.  It records changes in routes.

Their web site also has some tutorials on how to use pingplotter
to track down problems.

Unfortunately it's windows only.  It will run under vmware though.

I have no affiliation with them.  I've just found it very useful.
