Hi @Hugo Fernando Miranda Morin ,
Firstly, If you have used “Azure Monitor agent” that is explained here then I would recommend you to use Azure Monitor Log Analytics agent as instructed here. The reason for it is “Azure Monitor Agent” still in preview and would be Generally Available by Jan/Feb 2021 and as informed in this section, currently only Azure VMs are supported and on-premises VMs, virtual machine scale sets, Arc for Servers, Azure Kubernetes Service, and other compute resource types are currently not supported.
Next, If you have “Azure Monitor Log Analytics agent on Windows machine” then you may have to check below things:
- As explained here, Change Tracking and Inventory requires linking a Log Analytics workspace to your Automation account so I recommend you to double check it. For a definitive list of supported regions, see Azure Workspace mappings. The region mappings don't affect the ability to manage VMs in a separate region from your Automation account.
- Follow this troubleshooting steps in your case (i.e., if you don't see any Change Tracking and Inventory results for Windows machines that have been enabled for the feature).
- As mentioned here, note that currently Change Tracking and Inventory currently is experiencing the following issue w.r.t Windows environment: Hotfix updates aren't collected on Windows Server 2016 Core RS3 machines.
