I have two network interfaces graphed, they should be 95 pct billed as one.
Algorithm should be: - sum all inputs as one and all outputs as another "graph" - calc the 95pct for each "graph" - finally take the highest of those two. I need to make a HRULE showing the highest 95 percentile, input or output. I have tried: (a bit silly names around, they are machine generated) DEF:D_1=interface-12.rrd:InOctets:AVERAGE DEF:D_2=interface-11.rrd:InOctets:AVERAGE CDEF:C_Input=0,D_1,+,D_2,+,8,* VDEF:V_Input_AVERAGE=C_Input,AVERAGE VDEF:V_Input_MAXIMUM=C_Input,MAXIMUM LINE2:C_Input#00FF00:Input GPRINT:V_Input_AVERAGE:AVERAGE %6.2lf%s GPRINT:V_Input_MAXIMUM:MAXIMUM %6.2lf%s\\l DEF:D_3=interface-12.rrd:OutOctets:AVERAGE DEF:D_4=interface-11.rrd:OutOctets:AVERAGE CDEF:C_Output=0,D_3,+,D_4,+,8,* VDEF:V_Output_AVERAGE=C_Output,AVERAGE VDEF:V_Output_MAXIMUM=C_Output,MAXIMUM LINE2:C_Output#0000FF:Output GPRINT:V_Output_AVERAGE:AVERAGE %6.2lf%s GPRINT:V_Output_MAXIMUM:MAXIMUM %6.2lf%s\\l VDEF:V_Input95=C_Input,95,PERCENT VDEF:V_Output95=C_Output,95,PERCENT VDEF:V_total95=V_Input95,V_Output95,MAX # <-- this one fails! HRULE:V_Input95#009900:Input 95PCT HRULE:V_Output95#000099:Output 95PCT HRULE:V_total95#FF0000:total 95PCT It fails with: variable 'V_Input95' not DEF nor CDEF in VDEF 'V_total95' I cannot use a VDEF on VDEF's it seems... Suggestions? -- /Morten %-)
