HI,gord

Thanks for your infomation.
But I think vmware driver already support my requirement because It's docs
indicate it's already support the counter.
Maybe just the vsphere inspector in ceilometer haven't implement the
interface or we need add some other configuration in ceilometer.
So, is there any one know something about vsphere inspector in ceilometer
can give me some advice?
And I'll try to contact some developers on vmware driver for some help.
