function Get-DbaTraceFlag { <# .SYNOPSIS Get global Trace Flag(s) information for each instance(s) of SQL Server. .DESCRIPTION Returns Trace Flags that are enabled globally on each instance(s) of SQL Server as an object. .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 Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER TraceFlag Use this switch to filter to a specific Trace Flag. .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: TraceFlag Author: Kevin Bullen (@sqlpadawan) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT References: https://docs.microsoft.com/en-us/sql/t-sql/database-console-commands/dbcc-traceon-trace-flags-transact-sql .LINK https://dbatools.io/Get-DbaTraceFlag .EXAMPLE PS C:\> Get-DbaTraceFlag -SqlInstance localhost Returns all Trace Flag information on the local default SQL Server instance .EXAMPLE PS C:\> Get-DbaTraceFlag -SqlInstance localhost, sql2016 Returns all Trace Flag(s) for the local and sql2016 SQL Server instances .EXAMPLE PS C:\> Get-DbaTraceFlag -SqlInstance localhost -TraceFlag 4199,3205 Returns Trace Flag status for TF 4199 and 3205 for the local SQL Server instance if they are enabled. #> [CmdletBinding()] param ( [parameter(Position = 0, Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential] $SqlCredential, [int[]]$TraceFlag, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $tflags = $server.EnumActiveGlobalTraceFlags() if ($tFlags.Rows.Count -eq 0) { Write-Message -Level Output -Message "No global trace flags enabled" return } if ($TraceFlag) { $tflags = $tflags | Where-Object TraceFlag -In $TraceFlag } foreach ($tflag in $tflags) { [pscustomobject]@{ ComputerName = $server.ComputerName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName TraceFlag = $tflag.TraceFlag Global = $tflag.Global Session = $tflag.Session Status = $tflag.Status } | Select-DefaultView -ExcludeProperty 'Session' } } } } |
