[mrtg] Re: Removing a "blip"?

[Stieers, Ken]

Clearing the "blip" from the log should be enough.  You only have to delete
the gifs if you want to see it right away.  By the next morning the gifs
will have all been regenerated (some aren't genereated every run - ex.  the
yearly only gets generated once a day).

I hate when that happens.

You can set MaxBytes to something lower than the peaks to chop it 
off. I don't know if it works retroactively. The trouble with that is 
that when you legitimately hit a peak that high, MaxBytes will chop 
it off too.

Or, you can go through a .log file to find the spike, then script 
something to blow it away in all your .log files. You'll also have to 
do it in the .old file, and I found that I had to delete the yearly 
graph too.

It was a major pain, and I wouldn't be surprised if the spike 
reappears in the graphs (I only just did this).
