Optional Parameters

-SqlInstance

The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher.

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-Credential

Alternative credential for connecting to Active Directory.

-AvailabilityGroup

The availability group to test. If not specified, all availability groups will be tested.

-Listener

The availability group listener to test. If not specified, all listeners will be tested.

-InputObject

Enables piped input from Get-DbaAvailabilityGroup.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
