[mrtg] Re: avoiding peaks

[Koelstra, J. (Jan)]

Richard,

Some ways to smooth peaks are the "logscale" and "secondmean" options.

For details see: http://people.ee.ethz.ch/~oetiker/webtools/mrtg/mrtg-reference.html

If I understand you correctly however you want to avoid the too-high value in your graph completely. To achieve this changing the maxbytes value is the only way to go. If you know for sure the maxbytes value will never be reached it is an option to lower the MaxBytes value in your config file. Be aware that this will make the percentage figures below the graphs useless (in case you have the percentage displayed).

HTH,

Jan.

Hello list,

I use mrtg with tap-devices, normally no problem, but when a hicup occurs somewhere it gets wrong data from snmpd. The result of this is that the graph is scaled down because of an enormous peak. I use "MaxBytes" but is there another option to smooth these peaks?
