Hello Mojtabe,

Happy New Year and welcome back in 2019 ;)

In PRTG's data-path there is a subfolder called "Monitoring Database", there you need to delete all folders named like 2022xxxx. By default the data-path would be "C:\ProgramData\Paessler\PRTG Network Monitor", there you should find folder "Monitoring Database".

Before deleting the mentioned folders, please stop services "PRTG Core Server" and "PRTG Probe". After deleting the folders and starting the services again, PRTG should start again recording data properly.

Kind regards,
