                                function Get-DbaAgHadr {

    <#

    .SYNOPSIS

        Gets the Hadr service setting on the specified SQL Server instance.

    .DESCRIPTION

        Gets the Hadr setting, from the service level, and returns true or false for the specified SQL Server instance.

    .PARAMETER SqlInstance

        The target SQL Server instance or instances.

    .PARAMETER 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.

    .PARAMETER 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.
