You might want to take a look at the Host sFlow daemon:

http://host-sflow.sourceforge.net/

It exports all the dom0 and domN statistics from xentop, along with
additional dom0 CPU, memory, disk and network I/O statistics, making
it easy to monitor all the servers in your live migration pool from a
central location, providing the data you would need for load
balancing.

The following article provides links to resources and tools for
developing applications that support the sFlow standard:
