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. 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.
