Alias
Required True

Default Value

Optional Parameters

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..

Alias
Required False
Pipeline false
Default Value
-Database

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

Alias
Required False
Pipeline true (ByPropertyName)
Default Value
-ExcludeDatabase

The database(s) to exclude.

Alias
Required False
Pipeline false
Default Value
-IncludeSystemDb

Switch to have the output include system database memory consumption.

Alias
Required False
Pipeline false
Default Value False
-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.

Alias
Required False
Pipeline false
Default Value False
