I think you'd be far better off with a generic trace such as strace.
They're made for precisely this kind of thing.

Having said that. what you could do with the hooks is to wrap them
in functions that add logging.  To do that with apache logging would
require the APR macros to be masked out.  Since you'd be adding=20
overhead to everything the server does, you'll never get it accepted
into the main source tree, unless you can at the very least make it
conditionally compile.
