Most people would just look at the router's own bandwidth measurement
or the one at the ISP's end if that is available.  I thought what made
your case uncommon was that you had multiple machines and multiple
routers and  wanted the measurements for each pairing even though the
packets go over the same interfaces with no inherent separation.   If
you added interfaces and subnets for each route you wanted to measure
separately the normal tools would work naturally.
