Hi, Is there a way to define automatically the format for some fields via a custom mapping? I’m talking about the BYTES or Percentage format. I dont want each time to manually set the mapping on a new installed elasticsearch index/machine. In other words - I want to be able to import my mapping into kibana and have it with the special percentage/bytes format for some fields. ---

The field formats are part of the Index Pattern documents in the `.kibana` index. Most of the time, saved objects in Kibana can be exported to a backup and then re-imported to restore the backup, but unfortunately, Index Pattern objects are not exported. There is an open issue in Github on this: [https://github.com/elastic/kibana/issues/4288](https://github.com/elastic/kibana/issues/4288) The alternative to using exported saved objects is to create a snapshot that includes your `.kibana` index. This is done using Elasticsearch APIs: [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-snapshots.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-snapshots.html) If you make a snapshot of your `.kibana` index, then you can restore that into newly installed clusters, and then you'll be able to preserve all index patterns and their formatted fields. Hope that helps! ---
