[mrtg] MRTG vs. Cricket

Are you polling v2? v2 uses 64 bit counters, versus 32 bit v1, which isn't enough for anything over like 600Mbps (I don't recall the actual rollover point).

I am hoping someone can help me out with this issue I am having..... I
am working on migrating from Cricket to MRTG. So far so good except
that the Cricket graphs are pretty spot on for a 5 minute interval while
the MRTG graphs are anywhere from 600 Mbps to 1 Gbps off at peak time.
For example, I have a 10-gig circuit that runs roughly at 7 Gbps a peak
time. Cricket graphs it damn near spot on. MRTG is off by almost a
I have checked the cron jobs and both services are running every 5
minutes. They are synced to NTP and the clocks are not off so they are
both seeing the exact same data. I have set up my CFG files to use the
64 bit counters.
I have Googled for answers but not a lot out there on this topic. I am
hoping this is something small I have missed and can easily be fixed.
Any ideas? Thanks in advance.
