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,

I've just upgraded Ovirt3.6 to 4.0.2 and I can't get the dashboard to work.

The dashboard page displays this error:

Could not fetch dashboard data. Please ensure that data warehouse is properly installed and configured.

Running on CentOS 7.2 PostgreSQL server 9.5.4 (remote)

I see these errors being generated in engine.log when I try to display the dash board

ERROR [org.ovirt.engine.ui.frontend.server.dashboard.DashboardDataServlet]

Google returned some hints that it's probably the postgresql java version, I did have 9.4.xxx installed bu have since downgraded to postgresql-jdbc-9.2.1002-5

I checked the class path generated by dwh-classpath.sh which seems to be using the correct JDBC driver.

# /usr/share/ovirt-engine-dwh/bin/dwh-classpath.sh run

:/usr/share/java/dom4j.jar:/usr/share/java/apache-commons-

collections.jar:/usr/share/java/postgresql-jdbc.jar

# rpm -qf /usr/share/java/postgresql-jdbc.jar postgresql-jdbc-9.2.1002-5.el7.noarch

Any suggestions on what to try next?

So I think the key here is that your database is remote. And looking at the logs it is not finding the URL for the remote database properly. If you look in /etc/ovirt-engine/engine.conf.d/10-setup-dwh-database.conf I suspect either the DWH_DB_URL is missing or incorrect. It should be something like: DWH_DB_URL="jdbc:postgresql://<remote_db_machine>:<port>/<db_name>? sslfactory=org.postgresql.ssl.NonValidatingFactory" db_name is usually something like ovirt_engine_history. IIRC we don't automatically configure this file for remote databases. Let me know if the file is missing, I can get you instructions on how to create it.
