I've installed Elasticsearch 6.4.1 and installed Kibana 6.4.1 Logstash 6.4.1, Packetbeat 6.4.1, and Filebeat 6.4.1 on our CentOS 7 x64 VMware VM. Reviewing the documentation on how to secure Elasticsearch here: https://www.elastic.co/guide/en/x-pack/6.2/security-getting-started.html#security-getting-started I started doing this because I was trying to integrate Packetbeat into Elasticsearch as was noted here: https://www.elastic.co/videos/getting-started-with-packetbeat?baymax=rtp&storm=beats&elektra=product&iesrc=ctr that Packetbeat would show up in the Kibana window, but it did not so I found that X-pack needed to be configured. Is this correct?
So I attempted to install an older version of X-Pack (6.2.4), because I didn't note that the page I was taken to gave me a different version. I subsequently received the 'ERROR: This plugin was built with an older plugin structure. Contact the plugin author to remove the intermediate "elasticsearch: directory within the plugin zip.' so I found that this will not work. Is it correct that Elasticsearch 6.4.1 has X-pack integrated? Also, please advise on what I need to do with X-pack if it is integrated so I can get Packetbeat working within Kibana.
