How does the Update Manager handle updates in the background?

Question

I am currently exploring the capabilities of Azure Update Manager and would like to understand what exactly happens in the background during an update.

• How does Azure Update Manager actually apply updates in the background? Does it simply execute Run Commands (e.g., similar to manually running apt-get update && apt get-upgrade on Linux)?
• Or does it use a different background process for managing updates?
• How can I view the exact commands or processes it executes during an update?

Any insights or references would be greatly appreciated!

Thanks in advance!

Hi,

Yes Azure Update Manager just executes commands relevant to the tool that is used for updating the linux packages. If that is apt-get it will use that. Generally only specific package names and versions will be updated to avoid any new packages that might have appeared after the latest assessment and having mismatch of what is selected in Azure Update Manager and what is installed on the machines. You can check the logs on the machine via this article Troubleshoot issues with Azure Update Manager to see what is being executed locally as commands.
