Thanks, Daniel.
>>>counter roll-overs. With 32 bit counters, you will have frequent rollovers. The speeds in the link stay usually below 40 megs. I am surprised one can get hit by rollovers so far from the 114-megs threshold, but since we re doing arithmetic, it could be some internal thing. Will try the way you suggest.

The best way to deal with this is to use rrdtool as the backend, and routers2.cgi as the front end, and do the math on the two RRDs, rather than the raw counters. -- Daniel J McDonald, CCIE #2495, CISSP #78281, CNX Austin Energy http://www.austinenergy.com _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
