Hello Gunther (and everyone else who asked),
that's a nice statistic there. Which tool did you use to generate the output?
As I indicated in my first message in this thread, it's something that I wrote for Monzoon. It works with two small Perl scripts, RRDtool (what else ;) and some PHP for the web interface. Since there does seem to be some interest in this after all, I'll clean it up a bit and make it available for downloading. I'll let you know on this list when it's ready.
Cheers,
Manuel
