`xpack.security.audit.outputs`

Specifies where audit logs are output. For example: `[index, logfile]` . The default value is `logfile` , which puts the auditing events in a dedicated file named `<clustername>_audit.log` on each node. You can also specify `index` , which puts the auditing events in an Elasticsearch index that is prefixed with `.security_audit_log` . The index can reside on the same cluster or a separate cluster.

what does index mean here? A collection of documents?
