function Get-DbaTrace { <# .SYNOPSIS Gets a list of trace(s) from specified SQL Server Instance .DESCRIPTION This function returns a list of traces on a SQL Server instance and identifies the default trace file .PARAMETER SqlInstance The target SQL Server instance or instances .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 Id The id(s) of the Trace .PARAMETER Default Switch that will only return the information for the default system trace .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: Garry Bargsley (@gbargsley), http://blog.garrybargsley.com Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaTrace .EXAMPLE PS C:\> Get-DbaTrace -SqlInstance sql2016 Lists all the trace files on the sql2016 SQL Server. .EXAMPLE PS C:\> Get-DbaTrace -SqlInstance sql2016 -Default Lists the default trace information on the sql2016 SQL Server. #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [int[]]$Id, [switch]$Default, [switch]$EnableException ) begin { # A Microsoft.SqlServer.Management.Trace.TraceServer class exists but is buggy # and requires x86 PowerShell.
