You can go to the settings of the sensor and activate the "Store Result" option. After one scanning interval log files (Result of Sensor XXX.Data.txt and Result of Sensor XXX.txt) will be created on the corresponding probe under "C:\ProgramData\Paessler\PRTG Network Monitor\Logs\sensors". Maybe you'll find some further information here.

If you want us to take a closer look, feel free to send us these log files as well as screenshots of the issue to [email protected]
