I recently discovered that the spark-line chart is not displayed in the dashboard of the ovirt admin page. As a result of looking up the code and query, the data of the calendar table in the ovirt_engine_history DB of ovirt-dwh was only available until 2021-01-01 00:00:00, so a query statement ( https://github.com/oVirt/ovirt-engine/blob/master/frontend/webadmin/modules/.... RIGHT OUTER JOIN of properties) was not getting the correct data. First, the existing "generate_series('2011-01-01 00:00'::timestamp, '2021-01-01 00:00', '1 hours')" part was temporarily modified and applied until 2051. , it was confirmed that the spark-line chart was displayed normally. For this, is there a way I can directly edit the file (https://github.com/oVirt/ovirt-dwh/blob/master/packaging/dbscripts/upgrade/0...) to commit or request a correction? I would like to know.
