There are commercial software tools which can report the information like Concord eHealth. You can snmp the mib yourself but it is pretty complex. QOS models can be difficult and hiarchical and there is a lot to measure and report. To make it more complex the oid's will change on every policy change so you need to script for this condition too.

There are some extensions for Cacti which are all somewhat buggy:

(also checkout this bonus link http://www.eatworms.org.uk/cacti/ for nbar and saa monitoring with cacti)

There is also an inncomplete script on http://cosi-nms.sourceforge.net/alpha-progs.html which is a nice start building your own script.

If you find something another good solution I like to hear from it.
