Description of problem:
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/frontend/src/main/resources/org/ovirt/engine/ui/frontend/server/dashboard/dao/HostDwhDAO.properties)RIGHT OUTER JOIN 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.
Version-Release number of selected component (if applicable):
Please modify the sql file so that spark-line chart is output without any problem in Dashboard.
Steps to Reproduce:
The documentation text flag should only be set after 'doc text' field is provided. Please provide the documentation text and set the flag to '?' again.
Data present in webadmin dashboard might be incorrect, but we don't loose anything. After fixing the calendar table, dashboard should be working again
The sparkline chart is visible again and it's showing correct data.
