function Get-DbaLinkedServer { <# .SYNOPSIS Gets all linked servers and summary of information from the sql servers listed .DESCRIPTION Retrieves information about each linked server on the instance .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential SqlCredential object to connect as. If not specified, current Windows login will be used. .PARAMETER LinkedServer The linked server(s) to process - this list is auto-populated from the server. If unspecified, all linked servers will be processed. .PARAMETER ExcludeLinkedServer The linked server(s) to exclude - this list is auto-populated from the server .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 Author: Stephen Bennett ( https://sqlnotesfromtheunderground.wordpress.com/ ) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Get-DbaLinkedServer .EXAMPLE Get-DbaLinkedServer -SqlInstance DEV01 Returns all Linked Servers for the SQL Server instance DEV01 #> [CmdletBinding(DefaultParameterSetName = 'Default')] param ( [Parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [object[]]$LinkedServer, [object[]]$ExcludeLinkedServer, [switch][Alias('Silent')]$EnableException ) foreach ($Instance in $SqlInstance) { try { Write-Message -Level Verbose -Message "Connecting to $instance" $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $sqlcredential } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $lservers = $server.LinkedServers if ($LinkedServer) { $lservers = $lservers | Where-Object { $_.Name -in $LinkedServer } } if ($ExcludeLinkedServer) { $lservers = $lservers | Where-Object { $_.Name -notin $ExcludeLinkedServer } } foreach ($ls in $lservers) { Add-Member -Force -InputObject $ls -MemberType NoteProperty -Name ComputerName -value $server.NetName Add-Member -Force -InputObject $ls -MemberType NoteProperty -Name InstanceName -value $server.ServiceName Add-Member -Force -InputObject $ls -MemberType NoteProperty -Name SqlInstance -value $server.DomainInstanceName Add-Member -Force -InputObject $ls -MemberType NoteProperty -Name Impersonate -value $ls.LinkedServerLogins.Impersonate Add-Member -Force -InputObject $ls -MemberType NoteProperty -Name RemoteUser -value $ls.LinkedServerLogins.RemoteUser Select-DefaultView -InputObject $ls -Property ComputerName, InstanceName, SqlInstance, Name, 'DataSource as RemoteServer', ProductName, Impersonate, RemoteUser, 'DistPublisher as Publisher', Distributor, DateLastModified } } } |
