Monitoring FreeBSD jails ?

Hi,

hobbit server: 4.2-beta-20060605 on a linux server.

I installed the client on a freebsd 6.1 box and it works fine.

Currently, there are 7 jails on the box and i m going to install the
hobbit client on each one.

but i d like to know if there ll be some external scripts in order to
monitore Freebsd jails without installing a client hobbit into each jails.
(there are some tools like "jexec" to execute command into jail without
logging on it).

Thanks
Regards,

Nicolas Lienard
