How to remove host field from output.

[TomonoriSoejima]

I noticed that the resulting file on s3 bucket comes with additional information namely timestamp and hostname.
Is this possible to ignore them?

• My sample config

input { stdin { } }


filter {

      mutate {
        remove_field => [ "host" ]
      }

}


output {
  stdout { codec => rubydebug }
  s3 {
    access_key_id => "minioadmin"
    secret_access_key => "minioadmin"
    endpoint => "http://127.0.0.1:9000"
    bucket => "logstash"
    additional_settings => {
          "force_path_style" => true
        }
  }
}

I was hoping to see
2020-07-30T00:39:35.197Z rice since host is removed by mutate filter, but I got
2020-07-30T00:39:35.197Z %{host} rice instead.
