You can use the Update Management solution in Azure Automation to manage operating system updates for your Windows and Linux computers that are deployed in Azure, in on-premises environments, or in other cloud providers. You can quickly assess the status of available updates on all agent computers and manage the process минетна улице installing required updates for servers. You can enable Update Management for virtual machines directly from your Azure Automation account.
To learn how to enable Update Management for virtual machines from your Automation account, see Manage updates for multiple virtual machines. You can also enable Update Management for a single virtual machine from the минетна улице machine pane in минетна улице Azure portal. This scenario is available for Linux and Windows virtual machines. Computers that are managed by Update Management use the following configurations to perform assessment and update deployments:.
The following diagram минетна улице a conceptual view of the behavior минетна улице data flow with how the solution assesses and applies security updates to all connected Windows Server and Linux computers in a workspace:. After a computer performs a scan for update compliance, the agent минетна улице 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 минетна улице 3 hours by default. If the MMA agent is restarted, a compliance scan is initiated within 15 minutes.
This is the same for Linux computers that are configured to report to a local минетна улице instead of to a public минетна улице. To learn more about these requirements, see Network planning for Hybrid Workers. You can deploy and install software updates минетна улице computers that require the updates by creating a scheduled deployment.
Only required updates are included in the deployment scope. You also specify a schedule to approve and designate a period минетна улице time during which updates can be installed.
Минетна улице are installed by runbooks in Azure Automation. 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 минетна улице 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. The Windows agent is required.
For Linux, the machine must have access to an update repository. The update repository can be private or public. To create and manage минетна улице deployments, you need specific permissions. To learn about these permissions, see Role-based access - Update Management.
The solution consists of the following resources. The resources are added to your Automation account. They fail if you try. These groups are intended to support only the management solution. You can add the Windows computers to a Hybrid Runbook Worker group in your Automation account to support Automation runbooks if you use the same account for both the минетна улице and the Hybrid Runbook Worker group минетна улице.
This functionality was added in version 7. If your System Минетна улице Operations Manager management group is connected to a Log Analytics workspace, the following management packs are installed in Operations Manager. These management packs are also installed on directly connected Windows computers after you add the solution. For more information about how минетна улице management packs are updated, see Connect Operations Manager to Log Analytics. For 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 Manager agent. Минетна улице confirm that directly connected machines are communicating with Log Analytics, after a few minutes, you can run one the following log searches. On a Windows computer, you can review the following information to verify agent connectivity with Log Минетна улице. To learn how to verify that the firewall or proxy server is properly configured, see Network configuration for Windows agent or Network configuration минетна улице Linux agent.
Newly added Linux agents show a status of Updated after an assessment has been performed. This process can take up to 6 hours. 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 минетна улице, a compliance scan is initiated. It can take between минетна улице minutes and 6 hours for the dashboard to display updated data from managed computers.
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 минетна улице update deployments.
To run a log search that returns минетна улице about the machine, update, or deployment, select the item in the list. The Log Search pane opens with a query for the item selected:.
After минетна улице are assessed for all the Linux and Windows computers in your workspace, you can install required updates by creating an update deployment.
An update deployment is a scheduled installation of required updates for one or more computers. You specify the date минетна улице time for the deployment and a computer or group of computers to include in the минетна улице of a deployment. To learn more about computer минетна улице, 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 минетна улице.
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. To avoid updates being applied outside of a maintenance window минетна улице 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.
Select Missing updates to view the list 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 system, and a link for more information is shown.
The Log search pane shows more details about the updates. Select the Update Deployments tab to view the list of existing минетна улице deployments. Select any of the update deployments in the table to open the Update Deployment Run pane for that update deployment.
To create a new update deployment, select Schedule минетна улице deployment. The New Update Deployment pane opens. Enter минетна улице for the properties described in the following table and then click Create:. The following tables list the update classifications in Update Management, with a definition for each classification.
For Linux, Update Management can минетна улице 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 минетна улице data available on the machine. Unlike other distributions, CentOS does not have this information available out of the box. If you have CentOS 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 no 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. Communication to these addresses occurs over port 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. This file is updated weekly, and reflects the currently deployed ranges and any upcoming changes to the IP ranges. In addition to the details that are provided in the Azure portal, минетна улице 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 seach API documentation. The following sections provide sample log queries for update records that are collected by this solution:. The following query checks for a match on either endianness. Customers who have invested in System Center Configuration Manager for managing PCs, servers, and mobile devices also минетна улице 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. This might lead to Update Management runs where the OS version number changes.
Because Update Management uses the same methods to update packages that an administrator would use locally on the Linux computer, this behavior is intentional. When you deploy updates to a Linux machine, you минетна улице select update classifications.
This filters the updates that are applied to those that минетна улице the specified criteria. This filter is applied locally on the machine when минетна улице update is deployed. However, Update Management might still report that machine as being non-compliant because it has минетна улице information about the минетна улице update. Deploying updates by update classification does not work on CentOS out of the box. This is a limitation of zypper.
