tool to manage resources



Hi all!
I'm looking for any tool that helps me to list server resources: I
mean, I need to have an updated list of cpu, memory, disks, installed
apps, ect of a data center.
I don't need a tool to do remote administration or complex tasks but
just a simple tool with only one feature...

Do you suggest me anything?

I'm creating a bash script that do that for me but it's quite long and
complex: moreover it could be a waste of time...if I found a useful
sw...

Thanks
.
