I am monitoring a value for which I don't know the possible maximum, which
I would like to express as a percentage.

Expected to be able to do something like this (MAX should be a valid CF):

        DEF:packets=fsth.rrd:freepackets:AVERAGE
        DEF:packetsMAX=fsth.rrd:freepackets:MAX
        CDEF:packetsPercent=packets,packetsMAX,/,100,*

Alas the second line is not valid.

What is the appropriate syntax for obtaining a maximum value?
