We are using the last PRTG version (18.104.22.16883), and the SQL v2 sensor seem to not work as expected. We defined a custom query to get 2 int values, and used the sensor channel mode to "difference". Unfortunatly it always return the current number received without any difference with the last values. We tried to define the channel mode to "absolute" too and it's the same. Is it a bug or something we missed in the configuration ?
Thanks for your help
