  Not really.  I view xen-tools as being a neat way of setting up
 new instances of Xen which can be used for anything you like.

  Once they're up and running what you do with them is up to you.

 (e.g I create a new instance everytime I try to backport a package
 from Sid -> Sarge, to make sure it is unsullied and has nothing that
 I don't expect installed.)

  Ultimately traffic counting I view as a runtime activity, and
 xen-tools I consider a setup activity.  There exist multiple
 existing solutions for counting traffic from interfaces such
 as net-acct, mtrg, and my personal favourite vnstat.

  Whilst I've written a few things to manage instances, such as
 xen-shell and argo these aren't really full-scale general purpose
 pieces of software .. yuet.

  There is the ability to see tx/rx data for each instance, but it
 does nothing more than parse the output of /proc - to get the same
 data as you would find anyway from "ifconfig [interface name]".

  Argo needs a rewrite to do more.  I'm partway into turning it
 into an RPC based service to make clients nicer and easier to
 write - CVS has been broken for a while whilst I stalled on it.
