#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Start-DbaTrace { <# .SYNOPSIS Starts SQL Server traces .DESCRIPTION Starts SQL Server traces .PARAMETER SqlInstance The target SQL Server instance .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Id A list of trace ids .PARAMETER InputObject Internal parameter for piping .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .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: Security, Trace Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .EXAMPLE PS C:\> Start-DbaTrace -SqlInstance sql2008 Starts all traces on sql2008 .EXAMPLE PS C:\> Start-DbaTrace -SqlInstance sql2008 -Id 1 Starts all trace with ID 1 on sql2008 .EXAMPLE PS C:\> Get-DbaTrace -SqlInstance sql2008 | Out-GridView -PassThru | Start-DbaTrace Starts selected traces on sql2008 #> [CmdletBinding(SupportsShouldProcess)] param ( [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [int[]]$Id, [parameter(ValueFromPipeline)] [object[]]$InputObject, [switch]$EnableException ) process { if (-not $InputObject -and $SqlInstance) { $InputObject = Get-DbaTrace -SqlInstance $SqlInstance -SqlCredential $SqlCredential -Id $Id } foreach ($trace in $InputObject) { if (-not $trace.id -and -not $trace.Parent) { Stop-Function -Message "Input is of the wrong type.
