Xen devel - Jul 2010 - VM_metrics.get_VCPUs_utilisation to percent of usage

Hello. I need to convert VM_metrics.get_VCPUs_utilisation to percent (i
need  summary usage of all vcpus in domU)

I i correctly understand - i need to do two requests and formula like
this

delay = 5 (5 sec)

first_result-second_result
---------------------------  = %
     delay*1000

Is that right? If not - can You provide to me formula to calculate vcpus
usega like displays in xentop ?

Thanks.
