I upgraded our 3 server DAG from Exchange 2013 CU9 to CU11 this past weekend. After doing so, some of the DAG Powershell sensors return an error. Deleting the sensor, restarting PRTG and redeploying the sensor doesn't clear the error.
Ex01 - database_A, database_B = Active. database_C, database_E = passive
Ex02 - database_C, database_D = Active. database_A, database_F = passive
Ex03 - database_E, database_F = Active. database_B, database_D = passive
The sensors for database_A and database_C return the following error: no result from remote system, check settings
This seems to be linked to these 2 Exchange databases as it's the sensors for the active and passive copies of these DB that fail. This problem doesn't seem to be server-specific as the sensors for the other DB work fine.
How can I troubleshoot what's going on with the sensors on these DB?
