Hello,

I'm one of the 2 authors of dtc-xen. You can see our project page here:

http://www.gplhost.com/software-dtc-xen.html

We do monitoring of network and CPU for each of the domU using RRDTool.
Here are some examples:

http://node6501.gplhost.com/dtc-xen/
http://node0110.gplhost.com/dtc-xen/
http://node3302.gplhost.com/dtc-xen/

We get the CPU information using "xm list"
We get the network usage using /proc/net/dev

It's nice already, but I'd like to add the I/O rate of each of my VMs as
well, to know which of them is taking too much bandwidth or hard drives.
Does one of you know where to get this information?

Thomas Goirand, GPLHost
