Here's a cheap first run of a client side ext script that will send 
xentop data to your Hobbit server.  It doesn't act on any of the data 
and cause alerts, but we plan to add that later on unless someone else 
beats us to it.

Run it as a Hobbit client ext script on your Dom0 (not on the Hobbit 
client running on the DomUs) and give the Hobbit user sudo access to 
xentop, and xentop data will be displayed under the "xen" column in 
Hobbit.  If anyone makes enhancements to it, please share them.
