there was never a generic patch with a sensible interface. If you are interested in the second axis thing, please, before you start coding, come up with a configuration method and discuss it on the developers list ... > I also found that the values in rrd seem to be stored as double float, > using 8 bytes each - however, using 64bit integer values would be more > precise (in terms of reproducable) and still enough for +/- 1e+19 ... > Counting bytes that would mean ~10 Exabytes ... > > For some of my projects I would prefer having integer values, especially > if you use the rrd not only for grahing, but for logging as well. > Are there any attempts in that direction? Since rrdtool does automatic resampling of data as it comes in, using integers for data storage does not seem to be a good idea. OTOH, if you use a counter type data source, rrdtool uses integer math to calculate the difference between two consecutive counter readings ... > If I'm going to try to implement that change myself - as the > author of that tool, Tobias, how would estimate the amount of > time needed?
