Final answer:
To deploy missing patches using Update Management, configure a Log Analytics workspace, install the Microsoft Monitoring Agent on the virtual machines, set Update Management settings within the Azure Automation account, and ensure the network configuration allows communication with Azure services.
Step-by-step explanation:
When using Update Management to patch Azure virtual machines, several things must be configured to successfully deploy missing patches:
- Firstly, ensure that your Azure virtual machine is linked to a Log Analytics workspace, which is required for Update Management to operate.
- Secondly, the Microsoft Monitoring Agent (MMA) must be installed on the virtual machines that you wish to manage. This agent collects data and sends it to your Log Analytics workspace.
- Thirdly, configure the necessary Update Management settings within the Azure Automation account connected to your workspace to specify which machines to target, schedule updates, and set maintenance windows.
- Finally, proper network configuration is required for the virtual machines to communicate with Azure services. This could involve configuring network security groups, firewalls, and ensuring access to required URLs.
By ensuring these components are correctly set up, Update Management can properly assess and deploy the necessary patches to your Azure virtual machines.
