If you don't use munin it is very easy to write a do the following;
write a small script around the following command
varnishstat -1 -f s_bodybytes s_hdrbytes (and probably some other
counters you like to see)
to get the amount of bytes at a given moment and schedule it in cron to
run every 5 minutes or so.

We are using Varnish 2.1.0-2 for about 4 weeks now and we like it!
Glad you like it :)
There is only one problem, how can we log the used bandwidth used by the
varnish daemon? Normally in Apache we can use the access logs but in varnish
there is only memory logging.
Can anyone tell me how to get the bandwidth used by a specific daemon?
There are a few different approaches. I'm sure there's some OS-method too,
but a common way of doing it is reading it from varnishstat, as that only
resets when Varnish restarts. The Munin plugin for Varnish does exactly
that (among other things).
Essentially executing varnishstat -1 on a regular interval. Could be read
directly from the shmlog too, but that's a bit more complicated.
