Removing fields from Index

Elastic Stack Beats
1

Hi sorry for bothering you everytime.

I upload some logs into elastic via filebeat, but there is some other information added to my original logs like the host name os kernel ..., and the main message become unformatted, i want to delete all the field that are unnecessary and only keep my original message in the initial form.

You can delete Fields in the Filebeat processor like

processors:
  - drop_fields:
      fields: ["agent", "log", "input", "host", "ecs" ]

Or, if you don't need the Host information in generally, you can remove this from your filebeat conf.

- add_host_metadata: ~

from Filebeat Configuration.

I'm new with elk, so i don't know where write this code

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",]
