Using what ?
What OS do you use ? Where are you applying the QoS ?

If you do the routing with a Linux box then I suggest visiting the 
Linux Advanced Routing Howto and in particular section 9 "Queueing 
Disciplines for Bandwidth Management".

You would probably be making extensive use of HTB queues, for which 
the documentation is at http://luxik.cdi.cz/~devik/qos/htb/

Once you have your queueing and prioritisation, you can then read the 
stats from 'tc' and stuff the numbers into one or more rrd files - I 
do this with a cron job.

If you are using different routers (eg Cisco), then you will need to 
learn how to do traffic shaping on those, and find out how to read 
the stats (probably with snmp and mrtg).
