[Users] Disk statistics

[Joop]

Hi All,

Because of an question on IRC I looked at 
/api/disks/long-disk-id/statistics but all values (datum) are ZERO. Its 
a disk of a VM that was running a dd if=/dev/vda of=/dev/null so I would 
expect something to show up (Did various webpage refreshes of the 
mentioned stats url). I also have ovirt-guest-agent running on that VM, 
in case it matters and the disk is on a NFS data domain.

What am I missing?

Regards,

Joop
