#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaMaxMemory { <# .SYNOPSIS Gets the 'Max Server Memory' configuration setting and the memory of the server. Works on SQL Server 2000-2014. .DESCRIPTION This command retrieves the SQL Server 'Max Server Memory' configuration setting as well as the total physical installed on the server. Results are turned in megabytes (MB). .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 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: MaxMemory, Memory 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 .LINK https://dbatools.io/Get-DbaMaxMemory .EXAMPLE PS C:\> Get-DbaMaxMemory -SqlInstance sqlcluster, sqlserver2012 Get memory settings for instances "sqlcluster" and "sqlserver2012".
