ELK 5.5.2 installed by manual
From kibana.yml:
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.
For some reason index gets cleared daily, and all visualisations and dashboards disappear
there are records from elasticsearch log:

probably there are some log rotation, but I've not found any info in the docs. how to save kibana settings?
