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.

Cheers
