function Get-DbaDbccMemoryStatus { <# .SYNOPSIS Gets the results of DBCC MEMORYSTATUS. Works on SQL Server 2000-2019. .DESCRIPTION This command is used to run the DBCC MEMORYSTATUS comand and collect results in a single usable recordset Reference: - https://blogs.msdn.microsoft.com/timchapman/2012/08/16/how-to-parse-dbcc-memorystatus-via-powershell/ - https://support.microsoft.com/en-us/help/907877/how-to-use-the-dbcc-memorystatus-command-to-monitor-memory-usage-on-sq .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 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: DBCC, Memory Author: Patrick Flynn (@sqllensman) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaMemoryStatus .EXAMPLE PS C:\> Get-DbaDbccMemoryStatus -SqlInstance sqlcluster, sqlserver2012 Get output of DBCC MEMORYSTATUS for instances "sqlcluster" and "sqlserver2012".
