Be aware that rrdtool stores all values as floating point and performs data aggregation and normalization. There are a number of posts in the list archive discussing ways to work around/prevent normalization and aggregation, and I recommend looking at them if you need your output data points to be exactly equal to the original input. Even if you follow these guidelines, you still may see rounding error due to the conversion to and from floating point. -Sam _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
