monitor remote rpm database

[Mulley, Nikhil]

Hi All ,
Happy Holidays :)

I want to know how can I monitor remote machines rpm database , so that when ever a user on that machine installs a new rpm on the system, thinking that I have root access to the remote machine .
when I tried to search in install.log which is in /root directory , it is created only when te distribution is installed and thereby not updated ,
Where is the path of the rpm database (gdbm) files that rpm maintains and how do I read them ( what could be the keys to read the gdbm files) and from them generate the reports and send a mail to root or a groupmail.

Regards,
Nikhil.
