[ovirt-users] Could not fetch dashboard data. Please ensure that data warehouse is properly installed and configured.

[Shirly Radco]

Hi,

Did you install ovirt-engine-dwh during the upgrade? Was it installed
before?
If it is installed , Can you please check the ovirt-engine-dwh.log file for
errors?
If not, It must be installed in order to view the Dashboards. It is
collecting the statistics used for the dashboards.

Best regards,
