Description Germano Veit Michel 2022-04-04 04:39:00 UTC
Description of problem:

Go to Virtualization -> Overview and scroll to the bottom. Watch "Storage Throughput". The statistics seem very wrong.

Version-Release number of selected component (if applicable):
4.10.5

How reproducible:
100%

Steps to Reproduce:
1. Create a VM, do some very little IO (i.e. dd 1G to disk)
2. Virtualization -> Overview
3. Watch Storage Throughput in the statistics at the bottom

Actual results:
* Wrong, impossible values that persist even after the write finished.

Expected results:
* Correct value

Additional info:
* Same is happening for "Node", just select "Node" instead of "VM"

Comment 6 Leon Kladnitsky 2022-10-26 20:57:19 UTC
As of v4.12.0-145, the metrics still show wrong figures. After performing "sudo dd if=/dev/urandom of=/root/test bs=1M count=2000 status=progress" the Storage throughput metrics are increased by only 2 Mb. Also the units are wrong.
