The fix is to move the condition 'host_status = 1' from the external query to the internal query. In Hosts/VMS Trend Dashboard the queries display less then 5/3 interfaces/disks because there are different disk/interface ID for the same disk/interface name. The fix is to add the name of the Host/VM next to the disk/interface nam, This way it will not be averaged by the name of the disk/interface but by the name of the disk/interface + the name of the host/vm Steps to Reproduce: 1. Go to 'oVirt Trend Dashboards' 2. go to ' Trend Dashboard'/'Hosts/VMS Trend Dashboard' 3. The wrong panels are: Trend: Five Most Utilized Hosts by Memory (over time) (BR4B) Five Most Utilized Hosts by CPU (over time) (BR4B) Hosts: Top 5 Busiest Ethernet Interfaces Tx and Rx Rates (over time) (BR2A) VMS: Top 5 Most Utilized Disks Read and Write Rates (over time) (BR10A) Top 3 Most Utilized Network Interfaces Tx and Rx Rates (over time) (BR10A) Screenshot 1 : present an example of the above panels when showing only 2 hosts ( instead of 5 hosts ). Five Most Utilized Virtual Machines by Memory (over time) (BR11) Five Most Utilized Virtual Machines by CPU (over time) (BR11) Screenshot 2 : present an example of the above panels when showing only 1 vm ( instead of 5 vms ). Notes for qe: In Trend Dashboard check and make sure that all four panels show 5 entities exactly no matter which period is selected (unless there are less than 5 entities in the cluster then it makes sense - you can see how many active entities there are by deleting the 'limit 5' line in the code). for hosts/vms trend dashboards check that all panels show 2 rates for 5/3 entities.
Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.

Verified in ovirt-engine-4.4.5.9-0.1.el8ev.noarch ovirt-engine-dwh-4.4.5.5-1.el8ev.noarch The Hosts & VMs Trend Dashboards now show all 5 hosts/VMs/disks or 3 NICs in the Top X Most Utilized panels.
