Hi Karli,

Sorry for the confusion, Initially I thought it is an issue from our side so posted like 'ignore it',

But this issue is from oVirt. So could you please help me.

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 should come down 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 Zero

Actual : All values retains the last known values when the VM was in UP state.

Thanks,

Hari

You've now made several posts about wanting help, but this completely contradicts it!

I don't get it, do you have an issue you want help with, or should everyone just ignore you?

/K

But How frequently we will collect the disk statistics and update in PostgreSQL?

Thanks,

Hari

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

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.
