Hi, I have a problem here, which as far as I can see is not resolvable by RRDTOOL, but still I would like to ask before I go and look for a way around:
Imagine that I have 4 fields in RRD Database, the data is saved with the resolution of 1 minute, here are the 5 readings (5 Min Data) Field R1 R2 R3 R4 R5 --------------------------------------------------- a 3 23 7 11 0 b 5 14 13 1 2 c 32 26 0 4 8 d 4 11 2 8 0 I want to graph MAX percentage which the field "a" makes out of sum of all fields, formula is easy: CDEF:total:=a,b,+,c,+,d,+ CDEF:percent:a,total,/,100,* And this formula will work well if the data is shown in a native resolution, the plot here will be (Numbers round up): 6.8 31 31.8 45.8 0 Now I want to plot data at lower resolution, that is: one pixel equals 5 minutes, but I still want to see the MAX which was ever reached during those 5 minutes in one pixel, that is I want my pixel to be set to 45.8 in this case. Unfortunately as far as I understand what RRDtool will do is take maxes of all fields during this period and calculate a final value out of those values: a:23, b:14, c:32, d:11 Which will result in a pixel value of: 28.7. Is there a way around this problem, besides of feeding precalculated "a" value into rrd database (Unfortunately quite a PITA in our case).
