You can measure with iptables counting rules on the squid box, something
like:

iptables -A INPUT -s machine1 -p tcp --dport 3128 
iptables -A INPUT -s machine2 -p tcp --dport 3128 
...

You could do this using linux advanced routing, see 

http://www.lartc.org/

for more than you want to know. I use a simple token bucket filter to
share out ADSL bandwidth more equitably when my other half is furiously
peer-to-peer filesharing (:

I always found logrotate to be simple to use and ideal for such things.
