Which version of the stack are you using?

- Before 6.3: Install X-Pack for Elasticsearch, Kibana, and Logstash — see [https://www.elastic.co/guide/en/x-pack/current/installing-xpack.html](https://www.elastic.co/guide/en/x-pack/current/installing-xpack.html)
- 6.3.0 or later: Get the default packages (not the OSS ones) and everything is already built in. You can just enable a trial or add your license.
