[rrd-users] MAX function in CDEF

[Radovan Turan]

Hi,

nobody on the comp.dcom.net-management was answer to me. I hope that
somebody from you will.

My part of the "rrdtool graph" arguments:

DEF:x1=/file/to/rrd/some_file.rrd:var1:AVERAGE
DEF:x2=/file/to/rrd/another_file.rrd:var1:AVERAGE
CDEF:y=x1,x2,MAX

And this is problem. By manual page, "CDEF:y=x1,x2,MAX" is the propper
function to select maximum of the values x1 and x2. But "y" is leaved
"UNKNOWN".

How is the propper usage of the "MAX" function in the CDEF ?


Thanks,
