Hi Team,
We are using the following API to collect the disk statistics,
https://X.X.X.2/ovirt-engine/api/
*disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics*
<https://X.X.X.2/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3db...
I found one issue in the disk statistics. In case If the Virtual Machine
has this disk (*2331bad7-71ec-4fad-95bb-2b3449f3dbda*) attached to it and I
perform some read / write operation in the VM and it increases the
corresponding disk level Read data rate / Write data rate /
disk.read.latency / disk.write.latency.
*Example*, I received the following values for this disk, But the problem
is even when I bring down the VM still the last known value is received
continuously.
*Is it a known issue Or any workaround is available? *
*Expected : All values should go to Zero*
*Actual : All values retains the last known values when the VM was in UP
state. *

Hi Team,
*Steps to reproduce :*
1) Attach the disk to any VM
2) Perform some read and write operation in the VM which will increase the disk
level - 'Read data rate / Write data rate / disk.read.latency /
disk.write.latency'
3) Now when I bring down the VM, all the disk statistics needs to be zero *But
it is still retaining with last known value when the VM was in UP state.*
*Expected : All values should go to ZeroActual : All values retains the
last known values when the VM was in UP state. *
Thanks,
Hari

These statistics give wrong result when the VM is down. Guys did you get
any update on this?
Any help is appreciated.
Thanks,
