Sorry Simone for this maybe stupid hint....did you define such a variable when
creating the database using 'rrdtool create .....' ?

Betreff: [rrd-users] R: Export values from RRD, possible?
Hello Serge!
Thank's for your answer, but it doesn't works, what's wrong?
Simply Example:
rrdtool graph -s -36800 "DEF:eth0_in=test.rrd:eth0_in:AVERAGE
DEF:eth0_out=test.rrd:eth0_out:AVERAGE" PRINT:eth0_in:AVERAGE:"%7.2lf %Sb/s"
Output:
ERROR: unknown variable 'eth0_in'
But I've defined it right
Thank's
Simon
