Hello, I'm looking to use Filebeat to ship logs to our ELK stack cluster. Editing the yml file, I tried this kind of configuration: > ``` > fields: > debug: true > banana: > split: chocolate > > ``` but when starting the beat it doesn't work: `CRIT Config error: Error reading config file: YAML config parsing failed on filebeat.yml: yaml: unmarshal errors: line 39: cannot unmarshal !!map into string. Exiting.` Is it possible to nest fields? If yes , how? I would like to group related custom fields and refer to them in logstash with the [fields][banana][split] reference. Thanks Bruno ---

Nested fields are supported in the yet to be released Filebeat 1.1; see [PR #506](https://github.com/elastic/beats/pull/506). You can download a nightly snapshot of something that should be very close to the final 1.1; see links in [Insufficient throughput from Filebeat](https://discuss.elastic.co/t/insufficient-throughput-from-filebeat/39564/5). ---
