Hello, I am monitoring the Microsoft Exchange DAG: two servers, three databases both enabled on one of the servers. The PRTG shows me that the databases that make up the DAG are in warning. On server A (preferred) the warning is: "active but not on the preferred server". On server B (backup) the warning is: "not active but this is the preferred server". Server A is preferred, and server B is the DAG backup. I do not understand why he is showing me these values. From the Exchange PowerShell command line, I could corroborate this data: ServerA (preferred server) - ServerB (backup server).

Hello,
Thank you for the KB-Post. Can you share a few screenshots showing both Overview- and Settings Tabs of these DAG-Sensors, as well as the Powershell output which contradicts the sensors?
Also, which exact PRTG Version are you using?
best regards.
