Sure it has. It asks mod_jk and mod_jk knows all about worker statistics
etc. and generates an HTML page.

host/port not needed (but doesn't harm either)

Do you have any virtual hosts? If so, you need to put the JkMountFile
into the virtual host, which handles your /jkmanager request.

If it doesn't work at all, set JkLogLevel to debug, restart httpd and
send a single request for /jkmanager. After that, post the contents of
the JkLogFile.

Rainer
