Hello Shashank,
                           is it on the hour? it sounds like it got a problem aggregating the samples to create the hourly samples.

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.

Regards,
              Paul S.

Hello Shashank,
                               it looks like it's had a problem for over 2 years, is the Data Warehouse database local or remote? is there a firewall port open?

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.

Hello Shashank,
                                I can't see any of your images and also it would be better to have the log file as text.
