Azure Activity Log

Subscription-level Azure log of control plane operations, such as who created, modified or deleted resources.

Definition

The Activity Log records write operations (PUT, POST, DELETE), service health events and policy events for a subscription, retained for 90 days. Diagnostic settings can send it to a Log Analytics workspace, storage or event hub for longer retention and analysis.

Example

An admin reviews the Activity Log to find who deleted a virtual network and when.

Exam tip

Activity Log covers the management plane; data plane access to storage or databases requires resource logs.
