[ixpmanager] Odd MRTG Reading

[Mike Hammett]

Should anyone be Googling for the answer:

For the number highlighted in red, put a number bigger than you should be seeing for real data. I went through and saw several eight digit numbers prefaced by a one, so I just put in 50000000. It cut off the spike and the graphs seem reasonable now. The yearly has a flat spoke for a couple months at the front, but that could be related to other things. *shrugs* That flat doesn't bother me.

I'd suggest editing the mrtg log files manually.
