The Azure Preview Portal now supports Audit Logs. These logs include all of the provisioning actions performed via the Azure Resource Manager, in addition to other actions that are related to managing Azure resources (for example, autoscaling). What you can see in the Preview Portal today is an early version of this feature that we have shipped to collect feedback. Over time, we are planning to enrich the content of these logs and also enhance the user experience for this feature in the Preview Portal. Currently, the retention period for these logs is 90 days.
