Hey,
you have to change the following Block in your filebeat.yml if you don't want to get any Host Information at the log lines
processors:
- add_docker_metadata:
# - add_host_metadata: ~
( -add_host_metadata_~ is commented out)
If you only want to remove special fields you have to add the the following to the proccessors Block in your filebeat.yml
processors:
- drop_fields:
fields: ["host.name", "ecs.version", "agent.version", "agent.type", "agent.id",]
