#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaCmsRegServerGroup { <# .SYNOPSIS Gets list of Server Groups objects stored in SQL Server Central Management Server (CMS). .DESCRIPTION Returns an array of Server Groups found in the CMS. .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Group Specifies one or more groups to include from SQL Server Central Management Server. .PARAMETER ExcludeGroup Specifies one or more Central Management Server groups to exclude. .PARAMETER Id Get group by Id(s). This parameter only works if the group has a registered server in it. .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: RegisteredServer, CMS Author: Tony Wilhelm (@tonywsql) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaCmsRegServerGroup .EXAMPLE PS C:\> Get-DbaCmsRegServerGroup -SqlInstance sqlserver2014a Gets the top level groups from the CMS on sqlserver2014a, using Windows Credentials. .EXAMPLE PS C:\> Get-DbaCmsRegServerGroup -SqlInstance sqlserver2014a -SqlCredential $credential Gets the top level groups from the CMS on sqlserver2014a, using alternative credentials to authenticate to the server. .EXAMPLE PS C:\> Get-DbaCmsRegServerGroup -SqlInstance sqlserver2014a -Group HR, Accounting Gets the HR and Accounting groups from the CMS on sqlserver2014a. .EXAMPLE PS C:\> Get-DbaCmsRegServerGroup -SqlInstance sqlserver2014a -Group HR\Development Returns the sub-group Development of the HR group from the CMS on sqlserver2014a. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [object[]]$Group, [object[]]$ExcludeGroup, [int[]]$Id, [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { $server = Get-DbaCmsRegServerStore -SqlInstance $instance -SqlCredential $SqlCredential -EnableException } catch { Stop-Function -Message "Cannot access Central Management Server '$instance'" -ErrorRecord $_ -Continue } $groups = @() if ($group) { foreach ($currentgroup in $Group) { Write-Message -Level Verbose -Message "Processing $currentgroup" if ($currentgroup -is [Microsoft.SqlServer.Management.RegisteredServers.ServerGroup]) { $currentgroup = Get-RegServerGroupReverseParse -object $currentgroup } if ($currentgroup -match 'DatabaseEngineServerGroup\\') { $currentgroup = $currentgroup.Replace('DatabaseEngineServerGroup\', '') } if ($currentgroup -match '\\') { $split = $currentgroup.Split('\\') $i = 0 $groupobject = $server.DatabaseEngineServerGroup do { if ($groupobject) { $groupobject = $groupobject.ServerGroups[$split[$i]] Write-Message -Level Verbose -Message "Parsed $($groupobject.Name)" } } until ($i++ -eq $split.GetUpperBound(0)) if ($groupobject) { $groups += $groupobject } } else { try { $thisgroup = $server.DatabaseEngineServerGroup.ServerGroups[$currentgroup] if ($thisgroup) { Write-Message -Level Verbose -Message "Added $($thisgroup.Name)" $groups += $thisgroup } } catch { } } } } else { Write-Message -Level Verbose -Message "Added all root server groups" $groups = $server.DatabaseEngineServerGroup.ServerGroups } if ($Group -eq 'DatabaseEngineServerGroup') { Write-Message -Level Verbose -Message "Added root group" $groups = $server.DatabaseEngineServerGroup } if ($ExcludeGroup) { $excluded = Get-DbaCmsRegServer $server -Group $ExcludeGroup Write-Message -Level Verbose -Message "Excluding $ExcludeGroup" $groups = $groups | Where-Object { $_.Urn.Value -notin $excluded.Urn.Value } } if ($Id) { Write-Message -Level Verbose -Message "Filtering for id $Id.
