Re: Monitor Apps upgrade to 2.2.4 - missing old data?
If you deleted the archived logs then the history is gone. There is no supported way to pull the data from the prior version of the monitor apps QVDs. (Though you can try. The easiest way to try would be to make a copy of the 'old' 2.0 QVDs and rename them to '2.2.0'.)
If you remove all the QVDs from the Qlik\Sense\Log folder, then when you next reload the 2.2.4 version of the Monitor Apps, the apps will create new QVDs based on the logs that exist in Qlik\Sense\Log and Qlik\Sense\Repository\Archived Logs\ folders.
