After many attempts and many uninstalls, (wiping of the ovirt_engine_history database,
removal of the associated database user, removal of all ovirt-engine-dwh folders and
configs in /etc, and so on...) and reinstalls, I can't figure out how to get Data
Warehouse to work properly. The dashboard isn't getting populated with data and this
error message constantly shows in Alerts and Events in the Web Administration console:
"ETL service sampling has encountered an error. Please consult the service log for
more details."
Also, the file /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log shows the following error
repeatedly:

I just finished updating to oVirt 4.1.5 earlier today. My Internet searches have not
provided me with any further insight. Has anyone else experienced this issue? Has anyone
else resolved this issue? What should I be looking at to start debugging this issue (a
section of the database perhaps...)?
Thanks,
Charles
