Any one of the following could cause it...

Counter rollovers
******Use 64bit counters if possible

missed polls
******remove 'UNKNASZERO' if you have it in your options
******increase the timeout, retries and backoff on polls
******See "Extended Host Name Syntax" in the docs for more info

Plus a few others, but those are the most common causes.

Subject: [mrtg] peaks!!!

Dear All,
i asked before for something to solve the problem on the sudden peaks
occuring in the mrtg graphs,,

The suggested solution was using a perl code called killspike.pl,,,

But unfortunately,this code can't solve the problem as it needs a specified
input value to limit the whole values 2 it if the exceeded this threshold..

But,that's not what i need,,i need something to solve peaks problem that
occur within the logical range of traffic,,,i.e. sometimes the mrtg give a
very small reading followed by a very large peak (within the normal
range),then the following values return very small which is completely

Do u have any suggestions or even explanation to this event??
