title: Kibana settings gets cleared daily
body: <p>ELK 5.5.2 installed by manual</p>
  
  <p>From kibana.yml: </p>
  
  <blockquote>
    <p>Kibana uses an index in Elasticsearch to store saved searches,
    visualizations and dashboards. Kibana creates a new index if the index
    doesn't already exist.</p>
  </blockquote>
  
  <p>For some reason index gets cleared daily, and all visualisations and dashboards disappear</p>
  
  <p>there are records from elasticsearch log:</p>
