View resource changes in the Azure portal (preview)
Important
The Change Analysis experience in the Azure portal is in preview and migrating from Azure Monitor to Azure Resource Graph. Previews are partially covered by customer support on a best-effort basis. As such, these features aren't meant for production use.
Change Analysis provides data for various management and troubleshooting scenarios, helping you understand which changes to your application caused which breaking issues. In addition to querying Resource Graph for resource changes, you can also view all changes to your applications via the Azure portal.
In this guide, you learn where to find Change Analysis in the portal and how to view, filter, and query changes.
Access Change Analysis screens
Change Analysis automatically collects snapshots of change data for all Azure resources, without needing to limit to a specific subscription or service. To view change data, navigate to All Resources from the main menu on the portal dashboard.
Select the Changed resources card. In this example, all Azure resources are returned with no specific subscription selected.
Review the results in the Changed resources blade.
Filter and sort Change Analysis results
Realistically, you only want to see the change history results for the resources you work with. You can use the filters and sorting categories in the Azure portal to weed out results unnecessary to your project.
Filter
Use any of the filters available at the top of the Change Analysis blade to narrow down the change history results to your specific needs.
You may need to reset filters set on the All resources blade in order to use the resource changes filters.
