Hi Ayansh,
as it's only changing the history database there isn't a
high risk and you can run it while your system is being used,
For piece of mind you can do a full backup before, or just backup the Data
Warehouse.

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

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.

Paul S.

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