^1^ Make sure to enable these [MySQL® settings](concepts/settings-list.md#dbms-cluster-settings): **Audit log** and **Audit log policy**. Enabling these settings may result in additional load on your cluster hosts, so we recommend testing your system in dev/stage environments first. Also, to enable them, you may need to restart your services, so make sure to select a time when the cluster load is minimal.
