[Xymon] File monitor not working in Xymon - using file list generated by wildcard

If there will always be files in that directory you might want to consider
getting rid of the -mtime argument to your find command. That way you will
always get a file returned and then your mtime test in analysis.cfg will
catch that the returned file, which should be the newest one in the
directory thanks to  the sort,  is too old.

Thanks,
Larry Barber
