There are three ways to skin this cat:
1. Turn on netflow and run the flowscan application instead of mrtg. Flowscan can be found at http://www.caida.org/tools/utilities/flowscan
2. Turn on netflow and parse the output of show ip cache flow to grab byte counters from the summary statistics for certain well-known ports. A quick and dirty html parser was posted on the list last week.
3. Write access-lists and use CAR to monitor the pieces you are interested in. CAR is described in detail at http://www.geocities.com/djmcdon1
