Hello Ayansh, It looks like the lastHourAgg is wrong is should be 2 hours before the runTime but is 1:30 hours before runtime. Try systemctl stop ovirt-engine-dwhd in ovirt_engine_history database UPDATE history_configuration set var_datetime = var_datetime - interval '24 hour' WHERE var_name = 'lastHourAggr'; UPDATE history_configuration set var_datetime = var_datetime - interval '1 day' WHERE var_name = 'lastDayAggr'; systemctl stop ovirt-engine-dwhd see https://www.mail-archive.com/users@ovirt.org/msg53055.html Regards, Paul Staniforth School of Built Environment Engineering and Computing.

I had to update the java memory usage as it was running out of heap memory. The defaults are DWH_HEAP_MIN=1g DWH_HEAP_MAX=1g see /usr/share/ovirt-engine-dwh/services/ovirt-engine-dwhd/ovirt-engine-dwhd.conf for settings.

Can you connect to the database from the engine machine? The credentials should be in /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup-database.conf as your using 4.3 the version of postgresql is 10 and using scl scl enable rh-postgresql10 "psql -h localhost -U ovirt_engine_history -d ovirt_engine_history" if it's using the standard user, database and is local.
