Any tools to monitor processes and resources consumed of virtual machines?

Hi all,

I need a tool that can retrieve information about used resources of each VM and their processes,

• I use KVM as hyper-visor开发者_运维问答
• I also need it to have a programming API

I know it is a tough request :), but any contribution is more than welcome !

Thanx

If you're running *NIX based guests, couldn't you script a set of ssh sessions to login to each guest and grab whatever information you need?

I've heard Nagios and other popular monitoring tools work on virtual machines in much the same way as on the real ones.
