Here's what I have, it seems to graph now, but I'm sure there's a
cleaner way to do it:

CDEF:vices=vicecast,UN,0,vicecast,IF \
CDEF:ices=icecast,vices,+,10000,* \

ices content now shows in the graph, currently vicecast process is off
so its current rrd updates are NaN.

Mark, thanks for the link, it did indeed help.
