Hi Team,

I have created a VM using oVirt, which is in UP state now.

1) I opened the guest console using oVirt

2) I want to get the statistics for disk so I tried to create and write some content in the file (say test.txt) in loop to increase the latency and bandwidth in disk.

3) I observed that CPU in VM statistics is increased to 100 % (This is a good news since I expected this also)

    But when I looked into the disk level statistics using the following API, I observe the data value as '0' always.

{
    "statistic": [
        {
            "kind": "gauge",
            "type": "decimal",
            "unit": "bytes_per_second",
            "values": {
                "value": [
                    {
                        "datum": 0
                    }
                ]
            },
            "disk": {
                "href": "/ovirt-engine/api/disks/3bc267c0-a797-4e98-8ae9-217671649287",
                "id": "3bc267c0-a797-4e98-8ae9-217671649287"
            },
            "name": "data.current.read",
            "description": "Read data rate",
            "href": "/ovirt-engine/api/disks/3bc267c0-a797-4e98-8ae9-217671649287/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/3bc267c0-a797-4e98-8ae9-217671649287",
                "id": "3bc267c0-a797-4e98-8ae9-217671649287"
            },
            "name": "data.current.write",
            "description": "Write data rate",
            "href": "/ovirt-engine/api/disks/3bc267c0-a797-4e98-8ae9-217671649287/statistics/2f23addd-4ebd-3d82-a449-c28778bc33eb",
            "id": "2f23addd-4ebd-3d82-a449-c28778bc33eb"
        }
    ]
}

Thanks,
