Cris,

Try using another open source software exclusively for monitoring your
bandwidth use.

There are lots of them (I use MRTG for monitoring almost everything in our
servers). Try it.

The use of interchange benchmarks is very useful (you can find it at the
site on-line documentation) but the best way for monitoring bandwidth, IMO,
is using a software, like MRTG.

Bye.
