Hi Shubham,
In case you do not need the DWH setup, you can disable the Dashboard
background queries via the ovirt-engine.conf.
Please, add the following file to your $DEV_OVIRT_PREFIX folder:
"$DEV_OVIRT_PREFIX/etc/ovirt-engine/engine.conf.d/99-no-dashboard.conf"
and add it the following content:
#
# Enable/disable updating the dashboard DB query caches at regular
intervals.
#
DASHBOARD_CACHE_UPDATE=false
This should stop the error message
Regards,
Maor

to Scott, devel
setting DASHBOARD_CACHE_UPDATE=false indeed stops the issue.
Thanks.

That exception is telling you it can't run the queries needed to populate
the
dashboard. Highly likely you don't have the DWH properly
installed/configured.
That still shouldn't give you just a blank page, the code is written to
display an error stating unable to display dashboard or something of that
nature.
