function Get-DbaAgListener { <# .SYNOPSIS Outputs the name of the Listener for the Availability Group(s) found on the server. .DESCRIPTION Default view provides most common set of properties for information on the database in an Availability Group(s). Information returned on the database will be specific to that replica, whether it is primary or a secondary. This command will return an SMO object, but it is the AvailabilityDatabases object and not the Server.Databases object. .PARAMETER SqlInstance The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). .PARAMETER AvailabilityGroup Specify the Availability Group name that you want to get information on. .PARAMETER Listener Specify the Listener name that you want to get information on. .PARAMETER InputObject Piped in Availability Group objects .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. .NOTES Tags: AG, HA, AvailabilityGroup, Listener Author: Viorel Ciucu (@viorelciucu) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaAgListener .EXAMPLE PS C:\> Get-DbaAgListener -SqlInstance sqlserver2014a Returns basic information on the listener found on sqlserver2014a .EXAMPLE PS C:\> Get-DbaAgListener -SqlInstance sqlserver2014a -AvailabilityGroup AG-a Returns basic information on the listener found on sqlserver2014a in the Availability Group AG-a #> [CmdletBinding()] param ( [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [parameter(ValueFromPipeline)] [string[]]$AvailabilityGroup, [string[]]$Listener, [object[]]$InputObject, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { $InputObject += Get-DbaAvailabilityGroup -SqlInstance $instance -SqlCredential $SqlCredential -AvailabilityGroup $AvailabilityGroup } if (Test-Bound -ParameterName Listener) { $InputObject = $InputObject | Where-Object { $_.AvailabilityGroupListeners.Name -contains $Listener } } $defaults = 'ComputerName', 'InstanceName', 'SqlInstance', 'AvailabilityGroup', 'Name', 'PortNumber', 'ClusterIPConfiguration' foreach ($aglistener in $InputObject.AvailabilityGroupListeners) { $server = $aglistener.Parent.Parent Add-Member -Force -InputObject $aglistener -MemberType NoteProperty -Name ComputerName -value $server.ComputerName Add-Member -Force -InputObject $aglistener -MemberType NoteProperty -Name InstanceName -value $server.ServiceName Add-Member -Force -InputObject $aglistener -MemberType NoteProperty -Name SqlInstance -value $server.DomainInstanceName Add-Member -Force -InputObject $aglistener -MemberType NoteProperty -Name AvailabilityGroup -value $aglistener.Parent.Name Select-DefaultView -InputObject $aglistener -Property $defaults } } } |
