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
Default value
Accept pipeline input? False
Accept wildcard characters? false
-SqlInstance [<Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>]
The target SQL Server instance or instances.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
<CommonParameters>
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see
about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).
