Hi! I have fileabeat and logstash to send Nginx data to elasticsearch. I do not have “host.name” field in my logs, but when I discover my index patterns, I see this field. Where does it come from? How does elasticsearch understand the hostname? Can someone explain this to me? ---

It's likely coming from Filebeat. ---

Could you please explain how it is configured automatically? Can I override it? ---
