Docker logs from Elasticsearch instance - every second unknown HTTP requests

Elastic Stack Elasticsearch

Does anybody know what those requests are? We run Kibana frontend and see this in every Elasticsearch container (Docker).

Every second.

Hello Oow4chah,

If you are talking about the /_bulk requests, it is the elasticsearch bulk api. Judging by the User-Agent header, it seems to be Logstash.
