Artikkel
05/22/2023

The SQL Server IaaS Agent extension (SqlIaasExtension) runs on SQL Server on Linux Azure Virtual Machines (VMs) to automate management and administration tasks.

This article provides an overview of the extension. See Register with the extension to learn more.

Overview

The SQL Server IaaS Agent extension enables integration with the Azure portal and unlocks the following benefits for SQL Server on Linux Azure VMs:

Compliance: The extension offers a simplified method to fulfill the requirement of notifying Microsoft that the Azure Hybrid Benefit has been enabled as is specified in the product terms. This process negates needing to manage licensing registration forms for each resource.
Simplified license management: The extension simplifies SQL Server license management, and allows you to quickly identify SQL Server VMs with the Azure Hybrid Benefit enabled using the Azure portal, Azure PowerShell or the Azure CLI:
- PowerShell
- Azure CLI
```
Get-AzSqlVM | Where-Object {$_.LicenseType -eq 'AHUB'}
```
```
$ az sql vm list --query "[?sqlServerLicenseType=='AHUB']"
```
Free: There is no additional cost associated with the extension.

Installation

Register your SQL Server VM with the SQL Server IaaS Agent extension to create the SQL virtual machine resource within your subscription, which is a separate resource from the virtual machine resource. Unregistering your SQL Server VM from the extension will remove the SQL virtual machine resource from your subscription but will not drop the actual virtual machine.

The SQL Server IaaS Agent extension for Linux is currently only available with limited functionality.

Verify extension status

Use the Azure portal or Azure PowerShell to check the status of the extension.

Azure portal

Verify the extension is installed by using the Azure portal.

Go to your Virtual machine resource in the Azure portal (not the SQL virtual machines resource, but the resource for your VM). Select Extensions under Settings. You should see the SqlIaasExtension extension listed, as in the following example:

Check the Status of the SQL Server IaaS Agent extension SqlIaaSExtension in the Azure portal

Azure PowerShell

You can also use the Get-AzVMSqlServerExtension Azure PowerShell cmdlet:

  Get-AzVMSqlServerExtension -VMName "vmname" -ResourceGroupName "resourcegroupname"

The previous command confirms that the agent is installed and provides general status information. You can get specific status information about automated backup and patching by using the following commands:

 $sqlext = Get-AzVMSqlServerExtension -VMName "vmname" -ResourceGroupName "resourcegroupname"
 $sqlext.AutoPatchingSettings
 $sqlext.AutoBackupSettings

Limitations

The Linux SQL IaaS Agent extension has the following limitations:

Only SQL Server VMs running on the Ubuntu Linux operating system are supported. Other Linux distributions are not currently supported.
SQL Server VMs running Ubuntu Linux Pro are not supported.
SQL Server VMs running on generalized images are not supported.
Only SQL Server VMs deployed through the Azure Resource Manager are supported. SQL Server VMs deployed through the classic model are not supported.
SQL Server with only a single instance. Multiple instances are not supported.

Privacy statement

When using SQL Server on Azure VMs and the SQL IaaS Agent extension, consider the following privacy statements:

Data collection: The SQL IaaS Agent extension collects data for the express purpose of giving customers optional benefits when using SQL Server on Azure Virtual Machines. Microsoft will not use this data for licensing audits without the customer's advance consent. See the SQL Server privacy supplement for more information.
In-region data residency: SQL Server on Azure VMs and SQL IaaS Agent Extension do not move or store customer data out of the region in which the VMs are deployed.
