function Get-DbaAgListener { <# .SYNOPSIS Returns availability group listeners. .DESCRIPTION Returns availability group listeners. .PARAMETER SqlInstance The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher. .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 AvailabilityGroup Specify the availability groups to query. .PARAMETER Listener Return only specific listeners. .PARAMETER InputObject Enables piped input from Get-DbaAvailabilityGroup. .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: AvailabilityGroup, HA, AG 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 sql2017a Returns all listeners found on sql2017a .EXAMPLE PS C:\> Get-DbaAgListener -SqlInstance sql2017a -AvailabilityGroup AG-a Returns all listeners found on sql2017a on sql2017a for the availability group AG-a .EXAMPLE PS C:\> Get-DbaAvailabilityGroup -SqlInstance sql2017a -AvailabilityGroup OPP | Get-DbaAgListener Returns all listeners found on sql2017a on sql2017a for the availability group OPP #> [CmdletBinding()] param ( [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string[]]$AvailabilityGroup, [string[]]$Listener, [parameter(ValueFromPipeline)] [Microsoft.SqlServer.Management.Smo.AvailabilityGroup[]]$InputObject, [switch]$EnableException ) process { if (Test-Bound -Not SqlInstance, InputObject) { Stop-Function -Message "You must supply either -SqlInstance or an Input Object" return } if ($SqlInstance) { $InputObject += Get-DbaAvailabilityGroup -SqlInstance $SqlInstance -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 } } } |
