Assuming your stack is all 8.7, an elasticsearch output will, by default, create a data stream, not an index. If you want to create an index instead then set `data_stream => false` on the output.

If you do want a data stream then you cannot set the index name (you would use the various [data\_stream naming options](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-data_stream_auto_routing)).

Also, when writing to a data stream the output will not load a template, but I believe a template is required. You would have to load it through one of elasticsearch's template APIs.
