Ok, I took the changes out. restarted xymon, waited a half hour, put them back in,  and it created the rrd file.

HOWEVER, it only put it in once, and no updates:

And the script runs every 5 minutes from clientlaunch.cfg.

Do you have RRD caching enabled? If so, you won't get data updated on disk until either:
a) the cache is poked, which should happen automatically a few seconds after showgraph.sh is executed when viewing this graph,
b) the maximum amount of caches values is exceeded (12 intervals, by default, IIRC), or
c) xymond_rrd is (gracefully) shut down

If (a) isn't happening, there might be a permissions issue with your rrdctl.* socket files... Must be writeable by apache user.
