+You can use <<enable-audit-logging,audit logging>> to record security-related
+events, such as authentication failures, refused connections, and data-access
+events.
+
+If configured, auditing settings must be set on every node in the cluster.
+Static settings, such as `xpack.security.audit.enabled`, must be configured in
+`elasticsearch.yml` on each node. For dynamic auditing settings, use the
+<<cluster-update-settings,cluster update settings API>> to ensure the setting is
+the same on all nodes.
