Hi Team,

I am trying to get the disk level statistics using oVirt with the following API,

/ovirt-engine/api/disks/{unique_disk_id}/statistics/

and I get this response :

}

I am able to get the disk write and read latency, write and read bandwidth.

But I am not able to find the postgresql tables used for these statistics in oVirt?
Could somebody let me know the statistics table for the disk?

Any help is much Appreciated.

Thanks,   
Harry
