title: Filebeat 7.5.1 Missing a step for custom index names config?
body: <p>I should be able to see a new custom index name <strong>dev-7.5.1-yyyy.MM.dd</strong> within Kibana, but instead it is still called filebeat. </p>
  
  <p>I have the following set it my <strong><em>filebeat.yml</em></strong> config file, which should allow me to see dev-* index in Kibana. However these are still indexing as filebeat-7.5.1-yyyy-MM.dd. Filebeat is running on a ec2 instance that can communicate with the elastic-search server on port 9200. </p>
  
  <pre><code>filebeat.inputs:
    - type: log
      enabled: true
      paths:
        - /var/log/*.log
  
  filebeat.config.modules:
    path: ${path.config}/modules.d/*.yml
    reload.enabled: false
  
  output.elasticsearch:
    hosts: ["my_es_host_ip:9200"]
    index: "dev-%{[agent.version]}-%{+yyyy.MM.dd}"
  
  setup.template.enabled: true
  setup.template.name: "dev-%{[agent.version]}"
  setup.template.pattern: "dev-%{[agent.version]}-*"
  </code></pre>
  
  <p>Is there step I'm missing? From reading over the the <a href="https://www.elastic.co/guide/en/beats/filebeat/current/configuration-template.html" rel="nofollow noreferrer">docs</a> and the <a href="https://github.com/elastic/beats/blob/master/filebeat/filebeat.reference.yml" rel="nofollow noreferrer">reference file</a>, I believe I have everything set correctly.</p>
  
  <p>Appreciate any advice.</p>
