Function Get-DbaStartupParameter { <# .SYNOPSIS Displays values for a detailed list of SQL Server Startup Parameters. .DESCRIPTION Displays values for a detailed list of SQL Server Startup Parameters including Master Data Path, Master Log path, Error Log, Trace Flags, Parameter String and much more. This command relies on remote Windows Server (SQL WMI/WinRm) access. You can pass alternative Windows credentials by using the -Credential parameter. See https://msdn.microsoft.com/en-us/library/ms190737.aspx for more information. .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER Credential Credential object used to connect to the Windows Server as a different Windows user. .PARAMETER Simple Shows a simplified output including only Server, Master Data Path, Master Log path, ErrorLog, TraceFlags and ParameterString .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Tags: WSMan, SQLWMI, Memory dbatools PowerShell module (https://dbatools.io) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
