Looking good. You do insert the values on one minute intervals and do not get bitten by interpolation. However, since not all significant digits are actually displayed there still is a chance you're really looking at 1.00000000000001 and similar values. > The following snippet gets me a graph that seems to have a value of 3 > for all time periods, when it should be 2. Your example does not show the time to pixel ratio. Maybe RRDtool is calculating an average (avg(2,2,2,3)==2.25). Maybe not. > $graph2 = "DEF:status=$rrdfile:status:AVERAGE "; get the rate, store into "status" > $graph3 = "CDEF:unknown=status,0,EQ,0,0,IF "; status,0,EQ ===> true or false if (status==0) then return 0 else return 0. --> always 0 > $graph4 = "CDEF:syncing=status,2,LT,0,status,IF "; status,2,LT ===> true or false if (status<2) then return 0 else return status > $graph5 = "CDEF:active=status,2,EQ,0,status,IF "; status,2,EQ ===> true or false if (status==2) then return 0 else return status > $graph6 = "CDEF:inactive=status,2,GT,0,status,IF "; status,2,GT ===> true or false if (status>2) then return 0 else return status > $graph7 = "AREA:active#00FF00:Active "; > $graph8 = "AREA:syncing#0000FF:Syncing "; > $graph9 = "AREA:inactive#FF0000:Inactive "; You don't seem to do anything with "unknown". Why bother to do that CDEF? Display: active; display 0 if the rate==2, else display the rate This seems backwards. Dito for the other items. I think you got "if" the wrong way around. a,b,c,IF ==> if (a==true) then return b, else return c. You need to display (for instance) 3 only if rate==3. Do not forget to compensate for small fractions (the 1.000000000001). HTH Alex -- Received on my linux server: "Increase the speed of your PC in minutes!
