rrd use really the formula "DeLog_L,LOG,4,*" The fractional part is lost. I updated a smaller rrd with some 1000 and get with dump: ... <row><v>1.0000000000e+003</v><v>2.7631021116e+001</v></row>
But it should be 30. The real formula is L=10*LOG10(Delog_L). Because there is no LOG10 I used 10/LOG(10)=4.342944819 So I changed the formula to LOG(Delog_L)*10/LOG(10): DS:L:COMPUTE:DeLog_L,LOG,10,*,10,LOG,/ and get <row><v>1.0000000000e+003</v><v>3.0000000000e+001</v></row> It is a bug, that decimal numbers are round to integer numbers?
