Stan, I do not know if it is the same "snoopy", but there is a PHP script listed on Sourceforge by this name.
http://sourceforge.net/projects/snoopy/
It has no webpage of its own, and there's almost no info for it.
The snoopy script would be run on your hosted website, where it will have the LAMP available that it needs to run. Your associate in your website will know how to run it.
Beware, that a "Highly critical" security alert #
SA32361 has been issued on this script (assuming this is the one referred to by Eugen), by the security site Secunia. See:
Snoopy "_httpsrequest()" Shell Command Execution Vulnerability
http://secunia.com/Advisories/32361/
and
Vulnerability Report: Snoopy 1.x
