Hello sns
Welcome to Microsoft Q&A Platform, thanks for posting your query here.
To automatically assign Virtual Machines to maintenance configuration and enable periodic assessment, you can use Azure Automation and Azure Monitor. Here are the high-level steps to achieve this:
Create an Azure Automation account and a runbook to assign Virtual Machines to a maintenance configuration. You can use Azure PowerShell or Azure CLI to write the script for the runbook. The script should get the list of Virtual Machines that need to be assigned to a maintenance configuration and then assign them to the configuration.
Create an Azure Monitor alert to trigger the runbook periodically. You can create an alert based on a schedule or a metric. For example, you can create an alert that triggers the runbook every week to assign Virtual Machines to a maintenance configuration.
Create another runbook to enable periodic assessment for the Virtual Machines. The script for this runbook should enable the periodic assessment feature for the Virtual Machines that are assigned to a maintenance configuration.
Create another Azure Monitor alert to trigger the second runbook periodically. You can create an alert based on a schedule or a metric. For example, you can create an alert that triggers the runbook every month to enable periodic assessment for the Virtual Machines.
Test the runbooks and alerts to ensure they are working as expected.
By following these steps, you can automatically assign Virtual Machines to a maintenance configuration and enable periodic assessment for them.
Hope this helps.
