Description of problem: oVirt executive dashboard/Virtual Machine dashboard does not actually show disk I/O operations per second, but it shows sum of I/O operations since the boot time of VM. Version-Release number of selected component (if applicable): ovirt-engine-dwh-4.4.8-1.el8ev.noarch How reproducible: Always Steps to Reproduce: 1. Login to RHV Grafana UI and check 'Disk I/O operations/sec' in 'oVirt executive dashboard/Virtual Machine dashboard'. Actual results: 'Disk I/O operations/sec' in 'oVirt executive dashboard/Virtual Machine dashboard' shows sum of I/O operations since the boot time of VM. Expected results: 'Disk I/O operations/sec' in 'oVirt executive dashboard/Virtual Machine dashboard' should show I/O operations per second actually. Additional info:
I think this is filed against the wrong component. I am guessing this should be filed against vdsm or whoever writes the v4_4_statistics_vms_disks_resources_usage_samples table. read_rate_bytes_per_second is correct, read_ops_per_second is a sum, not an average per second, same for write
Verified in ovirt-engine-4.5.0.6-0.7.el8ev.noarch ovirt-engine-dwh-4.5.2-1.el8ev.noarch Second part of bug 2010903 In oVirt Executive Dashboards / 05 Virtual Machine Dashboard panel "Disk I/O operations since VM start (over time) (EX05-18)" has been renamed to say "since VM start" instead of previous "per second" which was incorrect.
