You are adding up different max values. Consider this set of data : a1 = 1 5 3 7 4 b1 = 2 6 9 1 4 If you do a graph of max (max a + max b) without any consolidation then you get the values : m1 = 2 11 12 8 8 If you consolidate 5 values into one, you then get : a2 ave = 4 a2 max = 7 b2 ave = 4.4 b2 max = 9 m2 (= max (max a2 + max b2)) = 16 So when you draw a graph over a longer time period, depending on the consolidation, you may see your maximum value go up (with these made up figures, by 1/3) when you add max values together. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
