Subject: XenAPI: why we implement VM_metrics.VCPUs_utilisation as proportion?
Date: Wed, 03 Sep 2008 17:20:14 +0800	[thread overview]
Message-ID: <48BE56CE.5060904@oracle.com> (raw)

hi all,

why we implement VM_metrics.VCPUs_utilisation as the proportion of all cpu time?

Then XenAPI client (xm) can not get the accumulated cpu_time of each vcpu.

I recommend we make VM_metrics.VCPUs_utilisation just the cpu_time which is
maintained by hypervisor.

Then XenAPI client (xm) not only can get the accumulated cpu_time of each vcpu,
but also can calculate the proportion by getting twice the
VM_metrics.VCPUs_utilisation.

Am I missing something?

thanks,

zhigang
