to test the non-existence of a dir

Hi,

Xymon allow me to test the non existence of file or directory. But I'd like a more complex test. In my case, I don't want any directory named _FIXED_PART_anything in a whole tree. Example :

I've /toto/_FIXED_PART_1 -> test is red /toto/a/sub/directory/_FIXED_PART_hello_world -> test is red

So, is there a "normal" way to use "files" test included in xymon ?
