Yes, it does, but you have to use follow=statistics on disks endpoint, see See http://ovirt.github.io/ovirt-engine-api-model/4.2/#documents/003_common_ concepts/follow
For all disks https://dipovirt-engine02.cnc.sk/ovirt-engine/api/disks?follow=statistic s

Ovirt API doesn't provide the API to get all the disk statistics at once. We need to hit for each Disk. It is an overhead.

May I ask what are you trying to achieve? Why not use the oVirt REST API? Y.

How frequently is the 'disk_all table' is updated with new statistics?

How is the disk id mapped to this table : disk_image_dynamic table?
If I need statistics of all the disk, How can I get it?

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
