I wrote a Perl script to poll `tc` for traffic control statistics (just bytes presently) for leaf qdiscs. The information is fed to either RRDTool or Munin[2], depending on what parameter is passed to the script. If the option for a RRD database is used, graphs[3][4] are written to disk for each ten second polling interval. If invoked via Munin[2], it handles graphing and samples at five minute intervals.

The script is available[5] here. The included README explains basic configuration. [5] http://trekweb.com/~jasonb/code/polltc-1.0.tar.gz I hope someone else finds it useful.
