When adding an Exchange Database DAG (PowerShell) sensor, unable to select available databases. What is the cause?
Available databases for monitoring Exchange server in a DAG with PRTG
The Exchange Database DAG (PowerShell) sensor is designed to monitor the Database Availability Group (DAG) status of a database on an Exchange server using Remote PowerShell.
Before sensor creation, make sure that you have a valid Database Availability Group (DAG) setup consisting of at least two servers in a DAG.
A database availability group (DAG) is the base component of the Mailbox server high availability and site resilience framework built into Microsoft Exchange Server. A DAG is a group of up to 16 Mailbox servers that hosts a set of databases and provides automatic database-level recovery from failures that affect individual servers or databases.
(cited on 2018/10/31, see the Microsoft Docs article Database availability groups for more information on DAG)
If you have only one Exchange server, you might want to browse our available mail server sensors for alternative Exchange sensors.
