[Xymon] integration of foreign graphs

[Martin Flemming]

Thanks a lot for answering !

David's suggestion was the hint which lead me to success,
although i don't wanted to create graph definitions for the rrd's,
because almost it sucks me :-)

Mark's solution is very interesting,
and if i've got some time i will test it also ..

jc's pointer i didn't understand it .. :-(
perhaps do you mean the option --extra-script for xymond_rrd ?

Thanks a lot & cheers
