Kibana can report conflicts in the Management / Kibana / Index Management : All Field Types Dropdown.

Is there a way to identify conflicts with one Elasticsearch API, so I can monitor proactively?

My understanding is that Kibana can do it because it looks across multiple indices based on the input pattern.

If Elasticsearch receives a conflict into an existing index, it'll reject the doc.

Thanks for quick response! That makes sense.

So, ES Logs would be the best place to find conflicts.
