We have added an Exchange Database DAG status sensor for each of the databases on our each of DAG members (Exchange 2010). The sensor has no problem showing all the databases and receives data for them successfully. However, the last message on all of the shows "This database is not a DAG-member".

Any idea why?

PRTG is version 16.1.21.1422

we are aware of the issue. We have seen this three or fore times so far but can not pinpoint to the source of the issue.

It could be a configuration or patch level issue.

In general the text can be ignored. The sensors work as they should regardless of this information text.

we are having this issue too and had my exchange adminstrator pondering it. also wanted to know what the powershell commands it was running and wanted to see what it was returning.

we are running latest exchange 2010 with all the SP and rollups.

Hi Googol,

PRTG will execute the 'Get-MailboxDatabaseCopyStatus' CMDlet. The This database is not a DAG-member message will be returned if there is no 'ActivationPreference' value.

Felix.

"Get-MailboxDatabaseCopyStatus" only returns ActivationPreference for Exchange 2013+

For Exchange 2010 the command is "Get-MailboxDatabase | Select Name, ActivationPreference, Server"

This explains why your sensor is broken on Exchange 2010

Cheers, Fernando

Hey Felix -

We are seeing the same issue. Using the Get-MailboxDatabaseCopyStatus CMDlet on the Exchange server does not return the parameter ActivationPreference. Can you provide the exact command that is being used?

Hi,

Does the command from Fernando work for you? Which Exchange version are you using?

Best regards, Felix
