Collecting the statistics of disk usage using oVirt

I used the REST-API to collect the statistics of a Virtual Disk using oVirt REST API and I got the following response, https://1.1.1.1/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/ Response to this ***API***, { "statistic": [{ "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "data.current.read", "description": "Read data rate", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/33b9212b-f9cb-3fd0-b364-248fb61e1272", "id": "33b9212b-f9cb-3fd0-b364-248fb61e1272" }, { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "data.current.write", "description": "Write data rate", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/2f23addd-4ebd-3d82-a449-c28778bc33eb", "id": "2f23addd-4ebd-3d82-a449-c28778bc33eb" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "disk.read.latency", "description": "Read latency", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/3a7b3f72-d035-3bb9-b196-e86a4eb34993", "id": "3a7b3f72-d035-3bb9-b196-e86a4eb34993" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "disk.write.latency", "description": "Write latency", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/b1e75c7b-cea4-37d2-8459-f7d68efc69a3", "id": "b1e75c7b-cea4-37d2-8459-f7d68efc69a3" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "disk.flush.latency", "description": "Flush latency", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/9c17ad7b-9ef1-3e8d-ad0a-ff8bee3925f0", "id": "9c17ad7b-9ef1-3e8d-ad0a-ff8bee3925f0" }] } So As per my understanding, It is able to retrieve 5 statistics (***i.e***) Read and Write Bandwidth, Read, Write and Flush Latency. My question is, Is it possible to get the ***READ / WRITE IOPS*** of virtual disk / VM? Thanks, Harry
