Update Management solution in Azure

You can use the Update Management solution in Azure Automation to manage секс екра system updates for your Windows and Linux computers that are deployed in Azure, in секс екра environments, or in other cloud providers. You can quickly assess the status of available updates on all agent computers and manage the process of installing required updates for servers.

You can enable Update Management for virtual machines directly from your Azure Automation account.

Секс екра

To learn how to enable Update Management for virtual machines from your Automation account, see Manage updates for multiple секс екра machines. You can also enable Update Секс екра for a single virtual machine from the virtual machine секс екра in the Azure portal. This scenario is available for Linux and Windows virtual machines.

Solution overview

Computers that are managed by Update Management use the following configurations to perform assessment and update deployments:

  • Microsoft Monitoring Agent секс екра for Windows or Linux
  • PowerShell Desired Секс екра Configuration (DSC) for Linux
  • Automation Hybrid Runbook Worker
  • Microsoft Update or Windows Server Update Services (WSUS) for Windows computers

The following diagram shows a conceptual view of the behavior and data flow with how the solution assesses and applies security updates to all connected Windows Server and Linux computers in a workspace:

Update Management can be used to natively onboard machines in multiple subscriptions in the same tenant.

To секс екра machines in a different tenant you must onboard them as Non-Azure machines.

After a computer performs a scan for update compliance, the agent forwards the information in bulk to Azure Log Analytics. On a Windows computer, the compliance scan is performed every 12 hours by default.

In addition to the scan schedule, the scan for update compliance is initiated within 15 minutes if the MMA is restarted, before update installation, and after update installation.

For a Linux computer, the compliance scan is performed every 3 hours by default.

Секс екра

If the MMA agent is restarted, a compliance scan is initiated within 15 minutes.

The solution reports how up-to-date the computer is based on what секс екра you're configured to sync with. If the Windows computer is configured to report to WSUS, depending on when WSUS last synced with Microsoft Update, the results might differ from what Microsoft Updates shows. This is the same for Linux computers that are configured to report to a local repo instead of to a public repo.


To properly report to the service, Update Секс екра requires certain URLs and ports to be enabled.

To learn more about these requirements, see Network planning for Hybrid Workers.

You can deploy and install software updates on computers that require the updates by creating a scheduled deployment. секс екра

Секс екра

Updates classified as Optional aren't included in the deployment scope for Windows computers. Only required updates are included in the deployment scope.

Секс екра

The scheduled deployment defines what target computers receive the applicable updates, either by explicitly specifying computers or by selecting a секс екра group that's based on log searches of a specific set of computers. You also specify a schedule to approve and designate a period of time during which updates can be installed.

Updates are installed by runbooks in Azure Automation. You can't view these runbooks, and the runbooks don’t require any configuration. When an update deployment is created, the update deployment creates a schedule that starts a master update runbook at the specified time for the included computers.

The master runbook starts a child runbook on each agent to perform installation of required updates.

At the date and time specified in the update deployment, the target computers execute the deployment in parallel.

Before installation, a scan is performed to verify that the updates are still required. For WSUS client computers, if the updates aren't approved in WSUS, the update deployment fails.


Supported client types

The following table shows a list of supported operating systems:

Operating секс екра Server 2008, Windows Server 2008 R2 RTMSupports only update assessments.
Windows Server 2008 R2 SP1 and секс екра Framework 4.5 or later is required.

Client requirements


Windows agents must be configured секс екра communicate with a WSUS server or they must have access to Microsoft Update.

You can use Update Management with System Center Configuration Manager. To learn more about integration scenarios, see Integrate System Center Configuration Manager with Update Management. The Windows agent is required. The agent is installed секс екра if you're onboarding an Azure virtual machine.


For Linux, the machine must секс екра access to an update repository. The update repository can be private or public. TLS 1.1 or TLS 1.2 is required to interact with Update Management.

An Operations Management Suite (OMS) Agent for Linux that's configured to report to секс екра Log Analytics workspaces isn't supported with this solution.

For information about how to install the OMS Agent for Linux and to download the latest version, see Operations Management Suite Agent секс екра Linux.

For information about how to install the OMS Agent for Windows, see Operations Management Suite Agent for Windows.


To create and manage update deployments, you need specific permissions.

To learn about these permissions, see Role-based access - Update Management.

Solution components

The solution consists of the following resources. The resources are added to your Automation account. They're either directly connected agents or in an Operations Manager-connected management group.

Hybrid Worker groups

After you enable this solution, any Windows computer that's directly connected to your Log Analytics workspace is automatically configured as a Hybrid Runbook Worker to support the runbooks that are included in this solution.

Each Windows computer that's managed by the solution is listed in the Hybrid worker groups pane as a System hybrid worker group for the Automation account.

The solutions use the naming convention Hostname FQDN_GUID. You can't target these groups with runbooks in your account. They fail if you try. These groups are intended to support only the management solution.

You can add the Windows computers to a Секс екра Runbook Worker group in your Automation account to support Automation runbooks if you use the same account for both the solution and the Hybrid Runbook Worker group membership.

This functionality was added in version 7.2.12024.0 of the Hybrid Runbook Worker.

Management packs

If your System Center Operations Manager management group is connected to a Log Analytics workspace, the following management packs are installed секс екра Operations Manager.

These management packs are also installed on directly connected Windows computers after you add the solution. You don't need to configure or manage these management packs.

  • Microsoft System Center Advisor Update Assessment Intelligence Pack (Microsoft.IntelligencePacks.UpdateAssessment)
  • Microsoft.IntelligencePack.UpdateAssessment.Configuration (Microsoft.IntelligencePack.UpdateAssessment.Configuration)
  • Update Deployment MP

For more information about how solution management packs are updated, see Connect Operations Manager to Log Секс екра systems with the Operations Manger Agent, to be able to be fully managed by Update Management, the agent needs to be updated to the Microsoft Monitoring Agent.

To learn how to update the agent, see How to upgrade an Operations Секс екра agent.

Confirm that non-Azure machines are onboarded

To confirm that directly connected секс екра are communicating секс екра Log Analytics, after a few minutes, you can run one the following секс екра searches.



On a Windows computer, you can review the following information to verify agent connectivity секс екра Log Analytics:

  1. In Control Panel, open секс екра Monitoring Agent.

    Секс екра

    On the Azure Log Analytics tab, the agent displays the following message: The Microsoft Секс екра Agent has successfully connected to Log Analytics.

  2. Open the Windows Event Log.

    Go to Application and Секс екра Logs\Operations Manager and search for Event ID 3000 and Event ID 5002 from секс екра source Service Connector. These events indicate that the computer has registered with the Log Analytics workspace and is receiving configuration.

If the agent can't communicate with Log Analytics and the agent is configured to communicate with the internet through a firewall or proxy server, confirm that the firewall or proxy server is properly configured.

To learn how секс екра verify that the firewall or proxy server is properly configured, see Network configuration for Windows agent or Network configuration for Linux agent.


If your Linux systems are configured to communicate with a proxy or OMS Gateway and you're onboarding this solution, update the proxy.conf permissions to grant the omiuser group read permission on the file by using the following commands:

Newly added Linux agents show a status of Updated after an assessment has been performed.

This process can take up to 6 hours.

To confirm that an Operations Manager management group is communicating with Log Analytics, see Validate Operations Manager integration with Log Analytics.

Data collection

Supported agents

The following table describes the connected sources that are supported by this solution:

Connected sourceSupportedDescription
Windows agentsYesThe solution collects information about system updates from Секс екра agents and then initiates installation of required updates.
Linux agentsYesThe solution секс екра information about секс екра updates from Linux agents and then initiates installation секс екра required updates on supported distributions.
Operations Manager management groupYesThe solution collects information about system updates from agents in a connected management group.
A direct connection from the Operations Manager agent to Log Analytics isn't required.

Data is forwarded from the management group to the Log Analytics workspace.

Collection frequency

A scan is performed twice per day for each managed Windows computer. Every 15 minutes, the Windows API is called to query for the last update time to determine whether the status has changed.

If the status has changed, a compliance scan is initiated.

A scan is performed every 3 hours for each managed Linux computer.

It can take between 30 minutes and 6 hours for the dashboard to display updated data from managed computers.

View update assessments

In your Automation account, select Update Management to view the status of your machines.

This view provides information about your machines, missing updates, update deployments, and scheduled update deployments.

In the COMPLIANCE COLUMN, you can see the last time the machine was assessed. In the UPDATE Секс екра READINESS column, you can see if the health of the update agent. If there's an issue, select the link to go to troubleshooting documentation that can help you learn what steps to take to correct the problem.

To run a log search that returns information about the секс екра, update, or deployment, select the item in the list.

Секс екра

The Log Search pane opens with a query for the item selected:

Install updates

After updates are assessed for all the Linux and Windows секс екра in your workspace, you can install required updates by creating an update deployment. An update deployment is a секс екра installation of required updates for one or more computers.

You specify the date and time for the deployment and a секс екра or group of computers to include in the scope of a deployment. To learn more about computer groups, see Computer groups in Log Analytics.

When you include computer groups in your update deployment, group membership is evaluated only once, at the time of schedule creation.

Subsequent changes to a group aren't reflected. To work around this, delete the scheduled update deployment and re-create it.


Windows virtual machines that are deployed from the Azure Marketplace by default are set to receive automatic updates from Windows Update Service.

This behavior doesn't change секс екра you add секс екра solution or add Windows virtual machines to your workspace.

Секс екра

If you don't actively manage updates by using секс екра solution, the default behavior (to automatically apply updates) applies.

To avoid updates being applied outside of a maintenance window on Ubuntu, reconfigure the Unattended-Upgrade package to disable automatic updates. For information about how to configure the package, see Automatic Updates topic in the Ubuntu Server Guide.

Virtual machines that were created from the on-demand Секс екра Hat Enterprise Linux (RHEL) images that are available in the Azure Marketplace are registered to access the Red Hat Update Infrastructure (RHUI) that's deployed in Azure.

Any other Linux distribution must be updated from the distribution's online file repository by following the distribution's supported methods.

View missing updates

Select Missing updates to view the секс екра of updates that are missing from your machines.

Each update is listed and can be selected. Information about the number of machines that require the update, the operating секс екра, and a link for секс екра information is shown. The Log search pane shows more details about the updates.

Update classifications

The following tables list the update classifications in Update Management, with a definition for each classification.


Critical updatesAn update for a specific problem that addresses a critical, non-security-related bug.
Security updatesAn update for a секс екра, security-related issue.
Update rollupsA cumulative set of hotfixes that are packaged together for easy deployment.
Feature packsNew product features that are distributed outside a product release.
Service packsA cumulative set of hotfixes that are applied to an application.
Definition updatesAn update to virus or other definition files.
ToolsA utility or feature that helps complete one or more tasks.
UpdatesAn update to an application or file that currently is installed.


Critical and security updatesUpdates for a specific problem or a product-specific, security-related issue.
Other updatesAll other updates that aren't critical in nature or aren't security updates.

For Linux, Update Management can distinguish between critical and security updates in the cloud while displaying assessment data due to data enrichment in the cloud.

For patching, Update Management relies on classification data available on the machine. Unlike other distributions, CentOS does not have this information available секс екра of the box. If you have Секс екра machines configured in a way to return security data for the following command, Update Management will be able to patch based on classifications.

There is currently секс екра method supported method to enable native classification-data availability on CentOS.

At this time, only best-effort support is provided to customers who may have enabled this on their own.


The following addresses are required specifically for Update Management.

Секс екра

Communication to these addresses occurs over port 443.

Azure PublicAzure Government

For more information about ports that the Hybrid Runbook Worker requires, see Hybrid Worker role ports.

It is recommended to use the addresses listed when defining exceptions.

For IP addresses секс екра can download the Microsoft Azure Datacenter IP Ranges. This file is updated секс екра, and reflects the currently deployed ranges and any upcoming changes to the IP ranges.

Search logs

In addition to the details that секс екра provided in the Azure portal, you can do searches against the logs. On the solution pages, select Log Analytics.

The Log Search pane opens.

You can also learn how to customize the queries or use them from different clients and more by visiting: Log Analytics секс екра API documentation.

Sample queries

The following sections provide sample log queries for update records that are collected by this solution:

Single Azure VM Assessment queries (Windows)

Replace the VMUUID value with секс екра VM GUID of the virtual machine you are querying.

You can find the VMUUID that should be used by running the following query in Log Analytics:

Missing updates summary
Missing updates list

Single Azure VM assessment queries (Linux)

For some Linux distros, there is a endianness mismatch with the VMUUID value that comes from Azure Resource Manager and what is stored in Log Analytics.

The following query checks for a match on either endianness. Replace the VMUUID values with the big-endian and little-endian format of the GUID to properly return the results. You can find the VMUUID that should be used by running the following query in Log Analytics:

Missing updates summary
Missing updates list

Multi-VM assessment queries

Computers summary

Integrate with System Center Configuration Manager

Customers who have invested in System Center Configuration Manager секс екра managing PCs, servers, and mobile секс екра also rely on the strength and maturity of Configuration Manager to help them manage software updates.

Configuration Manager is part of their software update management (SUM) cycle.

To learn how to integrate the management solution with System Center Configuration Manager, see Integrate System Center Configuration Manager with Update Management.

Patch Linux machines

The following sections explain potential issues with Linux patching.

Unexpected OS-level upgrades

On some Linux секс екра, such as Red Hat Enterprise Linux, OS-level upgrades might occur via packages.

This might lead to Update Management runs where the OS version number changes. Секс екра Update Management uses the same methods to update packages that an administrator would use locally on the Linux computer, this секс екра is intentional.

To avoid updating the OS version via Update Management секс екра, use the Exclusion feature.

In Red Hat Enterprise Linux, the package name to exclude is redhat-release-server.x86_64.

Critical / security patches aren't applied

When you deploy updates to a Linux machine, you can select update classifications.

This filters the updates that are applied to those that meet the specified criteria. This filter is applied locally on the machine when the update is deployed.

Because Update Management performs update enrichment in the cloud, some updates might be flagged in Update Management секс екра having security секс екра, even though the local machine doesn't have that information. As a result, if you apply critical updates to a Linux machine, there might be updates that aren't marked as having security impact on that machine and the updates aren't applied.

However, Update Management might still report that machine as being non-compliant because it has additional information about the relevant update.

Deploying updates by update classification does not work секс екра CentOS out of the box.

For SUSE, selecting only 'Other updates' as the classification may result in some security updates also being installed if security updates related to zypper (package manager) or its dependencies are required first. This is a limitation of zypper. In some cases, you may секс екра required to rerun the update deployment, to verify check the update log.
