No, normalisation is applied to ALL data types. Consider that you have a rate of 0 from time 0 to time 150, and a rate of 2 from time 150 to time 600 - and a step size of 300. From 0 to 300 you have half your bin at rate 0, and half at rate 2 - so the value stored for that bin is 1. From 300 to 600 the rate is uniform at 2, so 2 is stored. Note that I said rate. ALL values are rates in rrd - they are either calculated (eg at time 0 your counter was 0, at time 150 your counter was 0, at time 300 your counter was 300, and your data type is counter), or you supply a value which is already a rate and your data type is gauge. If you use data type gauge and supply updates of 0 at 0, 0 at 150, 2 at (some future time >=600), then the same process happens - the average rate from 0 to 300 is still 1. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
