 * API key usage isn't included in the audit log.
 
+* Users can be assigned the following Grafana Organization level roles: Admin, Editor, or Viewer. The Grafana Server Admin role isn't available to customers.
+

+* Azure Managed Grafana currently doesn't support the Grafana Role Based Access Control (RBAC) feature and the [RBAC API](https://grafana.com/docs/grafana/latest/developers/http_api/access_control/) is therefore disabled.
