Hello again guys. I would like to know a good server statistics script that tells

What all is installed on server(software wise)
What is specs of server (hardware wise)
When and how long the server's uptime is.

I think there is phpsysinfo but thats not what I am looking for.

And one more thing...

I get several requests about JSP, TOMCAT, and others. What are some other addons your clients ask for. Also, is there an installer that installs alot of these in a package? I think there is something called gentoo install but I am not sure.
