I’ve been using the Dude for a couple years now without any problems, but recently a couple of my routers are starting to report inaccurate bandwidth. They will start to graph about 1/3 of what is actually going through those routers. If I open up the bandwidth graph and click ok it starts graphing normally. Heres a screen shot to show you what I am seeing. One of the routers is a mikrotik router and the other is an imagestream router. Any ideas what might cause this in the dude? I tried turning off graphing and starting over (thinking maybe the data was too large) but that didn’t help.

Are the 32 bit counters rolling over? what is your polling interval? If you half the polling interval the counters might not roll over.
I wish the dude used 64bit counters.
I’ve tried slowing down poling, even deleting the modules and re-adding. It’s only happen on 2 routers and these are the 2 with the most bandwidth, 100-200 megs. Could that be the problem?
I still don’t understand how it could handle the one interval when the counter actually does roll over but I believe polling more often will give more accurate results… This is the reason why any new work on the dude should include an option to prefer 64bit counters.

Ok, so I changed the map to 1 minute intervals and now it’s working, but didn’t work on longer intervals. I don’t get it, but I suppose that’ll work. This is version 3.6 by the way.
