Recently we upgraded to MRTG 2.12.2, which has the logscale option. I tried it and indeed the vertical scale changes. But I wonder what scale is actually used. I was surprised that there is always a 0 at lower end of the Y axis, although a 0 cannot be shown on a true log scale. E.g, I have a graph with on the vertical axis the following numbers at the tick marks (from top to bottom): 5.1 M, 1.6 M, 0.5 M, 0.1 M and 0.0 M. I would expect a constant factor between these numbers for a log scale, which seems to be something close to 3. However, in that case the number at the low end should have a value of about 30 k. This would explain why on many graphs I still do not see the background, but only the peaks. It seems that everything 200 times smaller the highest peak is not visible. I would like to have a greater factor between the number at the tick marks, so that the background becomes visible.
My questions are: Is a real log-scale used, or is it an approximation with a few linear segments to save computing power? How is the factor between the tick marks calculated and can this be changed? _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
