 * Querying Azure Data Explorer may take a long time or return 50x errors. To resolve these issues, use a table format instead of a time series, shorten the time duration, or avoid having many panels querying the same data cluster that can trigger throttling.
 
-* 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.
 
 * Some Data plane APIs require Grafana Server Admin permissions and can't be called by users. This includes the [Admin API](https://grafana.com/docs/grafana/latest/developers/http_api/admin/), the [User API](https://grafana.com/docs/grafana/latest/developers/http_api/user/#user-api) and the [Admin Organizations API](https://grafana.com/docs/grafana/latest/developers/http_api/org/#admin-organizations-api).
