Hello all,
I'have some trouble with the grapha and the caption... as you can see regarding the Inbound traffic for the max I can read 58.1 Mb but... regarding the graphic there is no peak bigger than 30Mb ...
i'am begging you... help me. I have to make a report I don't realy understand this strange thing... It's make all my graphs
Cheers

Most likely due to consolidation. read http://docs.cacti.net/manual:087:8_rrdtool#rrdtool

No, not upgrade rrdtool. read about how rrdtool consolidates data over time. This is also covered in the rrdtool manual.

I had the same problem...
The issue is with how RRDTool consolodates the data for graphing, not how it's stored in the RRD file itself.
I'm working on documentation that I hope to share with everyone that better explains this.
Bottom line is that you need to change your graph lines to use the "MAX" consolidation function so that all your peaks are preserved.
The term "MAX" here doesn't really mean what I would have thought it did.... what it really means is this:
When you have to graph something and there are MORE data points available than pixels, use the highest value to represent the point on the graph. If you set it to AVG, it will take the average of all the data points that fit in that pixel space, so if the values are changing often, the average will 'artificially' lower the real peak.
Personally I don't find plotting anything BUT the MAX useful, I think it should be the default.
