For more information, see the SQL Assessment API overview (/sql/tools/sql-assessment-api/sql-assessment-api-overview).</maml:para> <maml:para>This cmdlet accepts the following input types:</maml:para> <maml:para>- Microsoft.SqlServer.Management.Smo.Server</maml:para> <maml:para>- Microsoft.SqlServer.Management.Smo.Database</maml:para> <maml:para>- Microsoft.SqlServer.Management.Smo.AvailabilityGroup</maml:para> <maml:para>- Microsoft.SqlServer.Management.Smo.FileGroup</maml:para> <maml:para>- Microsoft.SqlServer.Management.Smo.RegisteredServers.RegisteredServer</maml:para> <maml:para>- String containing path to any object of the above types</maml:para> <maml:para>- Collection of objects</maml:para> <maml:para></maml:para> <maml:para>You can get input objects with SqlServer cmdlets like Get-SqlInstance and Get-SqlDatabase or basic PowerShell cmdlets like Get-Item and Get-ChildItem. Also, the cmdlet supports the SQL Server PowerShell provider, so it can obtain an object from its path. The path can be passed explicitly, otherwise the current path will be used.</maml:para> <maml:para>Availability of a check for a chosen object varies on the SQL Server version, platform, and object type. Also, there are checks that target specific databases like `tempdb` or `master`. You can additionally filter checks by tags, names, and severity with the parameters -MinSeverity and -Check.</maml:para> <maml:para>With Get-SqlAssessmentItem cmdlet, you can get a list of checks applicable to the given SQL Server object. Also, you can use this cmdlet's output as -Check argument for Invoke-SqlAssessment cmdlet.</maml:para> <maml:para>Custom configurations can be applied with the -Configuration parameter. Customization examples are available on Github (https://go.microsoft.com/fwlink/?linkid=2099023).</maml:para> <maml:para>SQL Server on Azure VM support</maml:para> <maml:para>With SQL Assessment cmdlets, you can assess an instance of SQL Server on Azure VM not only as on-prem SQL Server, but also with rules that are specific to SQL Server on Azure VM (ones that use information about the virtual machine configuration). For example, the AzSqlVmSize rule checks that the VM that hosts an instance of SQL Server on Azure VM is of recommended size.</maml:para> <maml:para>To use such rules, connect to Azure with Azure PowerShell Module (/powershell/azure/get-started-azureps) and make sure that the [Az.ResourceGraph](https://www.powershellgallery.com/packages/Az.ResourceGraph)module is installed. Sign in with Azure PowerShell (/powershell/azure/authenticate-azureps)before invoking SQL Assessment against a SQL Server on Azure VM instance. Example 13 shows the interactive sign in process and subscription selection.</maml:para> <maml:para>NOTE. It is possible to use Azure account connection persisted between PowerShell sessions, i.e. invoke Connect-AzAccount in one session and omit this command later. However, the current version of SQL Assessment cmdlets needs the Az.ResourceGraph module to be imported explicitly in this case: Import-Module Az.ResourceGraph</maml:para> </maml:description> <command:syntax> <command:syntaxItem> <maml:name>Get-SqlAssessmentItem</maml:name> <command:parameter required="false" variableLength="true" globbing="false" pipelineInput="True (ByValue)" position="10" aliases="Target"> <maml:name>InputObject</maml:name> <maml:description> <maml:para>Specifies a SQL Server object or a path to such an object.

In the first public preview Invoke-SqlAssessment returned AssessmentNote objects with properties CheckId and CheckName containing Check's ID and DisplayName respectively. In the second public preview the two properties were replaced with a single Check property providing much more data. Assuming $note was an object returned by Invoke-SqlAssessment , you can access check's ID as $note.Check.Id instead of $note.CheckId, or check's description as $note.Check.Description. You can use -FlattenOutput parameter to get results in the previous format with CheckId and CheckName. This parameter will also help to retain compatibility to some cmdlets like Write-SqlTableData . See examples 12-14 for more details. Invoke-SqlAssessment cmdlet's output is a list of violated best practices for every given SQL Server object. Use Description property to learn about the best practice and Message property to find out how it can be solved. Also, every check result contains a link to online documentation, which will help you figure out the issue better.</maml:para> <maml:para>SQL Server on Azure VM support</maml:para> <maml:para>With SQL Assessment cmdlets, you can assess an instance of SQL Server on Azure VM not only as on-prem SQL Server, but also with rules that are specific to SQL Server on Azure VM (ones that use information about the virtual machine configuration). For example, the AzSqlVmSize rule checks that the VM that hosts an instance of SQL Server on Azure VM is of recommended size.</maml:para> <maml:para>To use such rules, connect to Azure with Azure PowerShell Module (/powershell/azure/get-started-azureps) and make sure that the [Az.ResourceGraph](https://www.powershellgallery.com/packages/Az.ResourceGraph)module is installed. Sign in with Azure PowerShell (/powershell/azure/authenticate-azureps)before invoking SQL Assessment against a SQL Server on Azure VM instance. Example 16 shows the interactive sign in process and subscription selection.</maml:para> <maml:para>NOTE. It is possible to use Azure account connection persisted between PowerShell sessions, i.e. invoke Connect-AzAccount in one session and omit this command later. However, the current version of SQL Assessment cmdlets needs the Az.ResourceGraph module to be imported explicitly in this case: Import-Module Az.ResourceGraph</maml:para> </maml:description> <command:syntax> <command:syntaxItem> <maml:name>Invoke-SqlAssessment</maml:name> <command:parameter required="false" variableLength="true" globbing="false" pipelineInput="True (ByValue)" position="10" aliases="Target"> <maml:name>InputObject</maml:name> <maml:description> <maml:para>Specifies a SQL Server object or the path to such an object.
