the volume always stays 0. And also the same for the volume of disk.read.requests/disk.write.requests/disk.read.bytes

log can be found here(seems there r no errors related to disk pollster): http://paste.openstack.org/show/51911/

Expected: the volumes should be Cumulative. So it seems that the wmi does not collect the right values.

    Fixes Hyper-V Inspector disk metrics bug

    Changed disk metric names used by Hyper-V utils.

    Was using wrong metric names before. 'Aggregated Disk Data Read/Written'
    metrics refers to all disks (sum), while the metrics needs to be per disk.
