NAME Get-DbaDbMemoryUsage



SYNOPSIS

Determine buffer pool usage by database.





SYNTAX

Get-DbaDbMemoryUsage [-SqlInstance] <Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]> [[-SqlCredential]

<Pscredential>] [[-Database] <System.Object[]>] [[-ExcludeDatabase] <System.Object[]>] [-IncludeSystemDb <Switch>]

[-EnableException <Switch>] [<CommonParameters>]





DESCRIPTION

This command can be utilized to determine which databases on a given instance are consuming buffer pool memory.



This command is based on query provided by Aaron Bertrand.



Reference: https://www.mssqltips.com/sqlservertip/ ... nd-object/





PARAMETERS

-Database [<System.Object[]>]

The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will

be processed.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-EnableException [<Switch>]

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.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-ExcludeDatabase [<System.Object[]>]

The database(s) to exclude.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-IncludeSystemDb [<Switch>]

Switch to have the output include system database memory consumption.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-SqlCredential [<Pscredential>]

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..



Required? false

Position? named
