I recently updated the Windows server the PRTG core server runs on and I suddenly have the wrong messages in my sensors. The Windows update also restarted the server.
I use a lot of SNMP custom string sensors to get things like the name, description, location or contact of a device. Instead of displaying something like the name of a device they only display an OK as message. Every SNMP custom string sensor I have seen now displays just the OK message after the Windows update. I would have gone back a day using the auto config backup, but I just so happen to have activated a license on the same day I updated the Windows server.
I am not sure how rolling back to a back-up wil affect the license. Can I just go back to a previous configuration and re-enter the license or is there a solution to the SNMP custom string sensors only displaying an OK message instead of an actual string?
