Just to complete the thread, a new SNMP module is available for such purpose. In the announcement are listed several tools that can help to collect statistics and generate grphs. It is a matter of configuration and maybe small shell scripting:

At the first sight these tools can be used with FIFO or XMLRPC interface as well, if you write the shell script to collect the statistics.

You can make a small script to pull periodically statistics via FiFO/XMLRPC into a database/file and from there generate graphics at your convenience.

This is what I thought about. I expect that I'm not the only one who is interested in statistics. So maybe anyone else has done this job before. ;-)
