I have a working Ansible Playbook that installs the ELK stack (Elasticsearch, Logstash, Kibana and for this example, Filebeat) across three different computers.

It does not take much for a file / folder structure to become a bit messy, especially if it is a folder containing downloads. One of the common issues that can occur is for file extensions being lost or wrote over by mistake.
