I see, so this is shorthand for
    "--start end-$START" and "--end now-$END" ?
Didn't know that this worked:)

What remains in that case is to verify your setup.

1) do a "rrdtool dump" and verify the resulting xml file
2) use "rrdtool fetch" with the same start and end time
3) create an image by doing the "rrdtool graph" command
   yourself
4) debug the generated command line, for instance by doing
       echo rrdtool graph .....  >> /tmp/mycommand.txt
       rrdtool graph .....

cheers
