On my systems, I have some very fixed, low-bandwidth satellite links. With my old MRTG-like, poll-ifInOctet.x-every-minute routine, I seemed to have very accurate numbers that never exceeded my bandwidth cap. When I setup nfsen with filters for these same interfaces (IN IF x), I do get some values that spike over my known cap. Nothing seems to be sustained above the cap, but I do see some spikes that are clearly not quite right. The rest of the data seems to correlate with my old system fairly well (other than only being 5 minute intervals on nfsen...wish it could be 1min...) Id love to know what's up with the values that are obviously wrong, but I havent had a chance to dig into it.
