You can rate examples to help us … In contrast, hours, minutes, and seconds are well defined time intervals, and these are guaranteed to always produce time offsets exactly as specified (e.g. ds[proc].min = 0.0000000000e+00 *UNKNOWN* data is often represented by the string ``NaN'' depending on your OSs printf function. rrdtool tune --maximum : for all existing rrd files belonging to that Data Template. ds[proc].min = 0.0000000000e+00 The .rrd files look good when I use "rrdtool info".
