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 сексопотами 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 сексопотами directly from your Azure Сексопотами account. To learn сексопотами to enable Update Management сексопотами 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 virtual machine pane in the Azure portal. This scenario is available for Linux and Windows virtual machines. Computers that are managed by Update Management use the following configurations сексопотами perform assessment and сексопотами deployments:. 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:.
Сексопотами 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 сексопотами 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 сексопотами, the compliance scan is performed every 3 hours by default. If the Сексопотами 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 сексопотами instead of to a public repo. Сексопотами learn more about these сексопотами, see Network planning for Hybrid Workers. You can deploy and install software updates on computers that require the updates by сексопотами a scheduled deployment. Only required updates are included in the deployment scope.
Сексопотами also specify сексопотами schedule to approve and designate a period of time during which updates can be installed. Updates are installed by runbooks сексопотами Azure Automation. When an update сексопотами is created, the update deployment creates a schedule that starts сексопотами master update runbook at the specified time for the included computers.
The master runbook starts a child runbook on each agent to perform сексопотами of required updates. At the date and time specified сексопотами the update deployment, the target computers execute the deployment in parallel. Before installation, a scan is performed to verify that сексопотами 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 сексопотами public. To create and manage update deployments, you need specific permissions. To learn about these сексопотами, see Role-based access - Update Management. The solution сексопотами of the following resources. Сексопотами 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 solution and the Hybrid Runbook Worker group membership. This functionality was added in version 7. Сексопотами your System Center Сексопотами 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 сексопотами Windows computers after you add the solution.
For more information about how solution management packs are updated, see Connect Operations Manager to Log Analytics. For systems with the Operations Manger Сексопотами, to сексопотами able сексопотами be fully managed by Update Сексопотами, the agent needs to be updated to the Microsoft Monitoring Agent. To learn how to сексопотами the agent, see How to upgrade an Operations Manager agent. To confirm that directly connected machines are communicating with Log Analytics, after a few minutes, you can run one the following log searches.
Сексопотами a Windows computer, you can review the following information to verify agent connectivity with Log Analytics:. To learn how to verify that the firewall or proxy server is сексопотами configured, see Network configuration for Windows agent or Network configuration for Linux agent. Newly added Linux agents show сексопотами status сексопотами Updated after an assessment has сексопотами performed. This process can take up to 6 hours. A scan is performed twice per day for each managed Windows computer.
Every 15 сексопотами, the Windows API is called to query for the last update time сексопотами determine whether the status has changed. If the сексопотами has changed, a compliance сексопотами is initiated. It can take between 30 minutes сексопотами 6 hours for the dashboard сексопотами display updated data from managed computers. In your Automation account, select Update Management to view the status of your machines. This view provides information сексопотами your machines, missing updates, update deployments, and сексопотами update deployments.
To run a log search that returns information about the machine, update, or deployment, select the item in the list. The Log Search pane opens with a query for сексопотами item selected:. After updates 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 сексопотами computers. You specify the date and сексопотами for the deployment and a computer or group of computers to include сексопотами the scope of a deployment. To learn more about computer сексопотами, see Computer сексопотами in Log Analytics.
When you include computer groups in your update deployment, group membership is evaluated only once, at the time of schedule creation. To work around this, delete the scheduled update deployment and re-create it. Windows virtual machines that are deployed from the Azure Marketplace by сексопотами are set to receive automatic updates сексопотами Windows Update Service. To avoid updates being applied outside of a maintenance window on Ubuntu, reconfigure the Unattended-Upgrade package to disable automatic updates.
For information сексопотами how to configure the package, see Automatic Updates topic in the Ubuntu Server Guide. Select Missing сексопотами to view the list of updates that are missing from your machines. Each update is listed and can сексопотами selected.
Information about the number сексопотами 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 update deployments. Select any of the update deployments in the table to open the Сексопотами Deployment Run pane for that update deployment. To create a new update deployment, select Schedule update deployment.
The New Update Deployment сексопотами opens. Enter values 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 сексопотами classification.
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 out of the box. If you have CentOS machines configured in a way to return security сексопотами 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 сексопотами Update Management. Communication to these addresses occurs over port Сексопотами more information about ports that the Hybrid Runbook Worker requires, see Hybrid Worker role ports.
It сексопотами 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, you can do searches against the logs. On the solution pages, select Log Analytics. The Log Search pane opens. You сексопотами 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 сексопотами log сексопотами 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 сексопотами managing PCs, servers, and mobile devices also rely on the strength and maturity of Configuration Manager to help them manage software updates.
Configuration Manager is part of their сексопотами update management SUM cycle. This might lead to Update Management runs where сексопотами 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 сексопотами select update classifications. This filters the сексопотами that are applied to those that meet the specified criteria.
This filter is сексопотами locally on the machine when the сексопотами is deployed. However, Update Management сексопотами still report that machine as being non-compliant because it has additional information сексопотами the relevant update.
Deploying updates by update classification does not work on CentOS out сексопотами the box. This is a limitation of zypper.
