- type: log

  enabled: true

  paths:
    - /usr/local/logstash/sample/line.log
  fields:
    type: syslog  

#============================= Filebeat modules ===============================

filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: false

#==================== Elasticsearch template setting ==========================

setup.template.settings:
  index.number_of_shards: 3

setup.template.name: "filebeat-jay"
setup.template.pattern: "filebeat-jay-*"
setup.kibana:

  host: "localhost:5601"
  username: "elastic"

#-------------------------- Elasticsearch output ------------------------------

  hosts: ["localhost:9201"]
  index: "filebeat-jay-%{[beat.version]}-%{+yyyy.MM.dd}"
  indices: 
    - index: "filebeat-jay-debug-%{[beat.version]}-%{+yyyy.MM.dd}" 
      when.contains:
        message: "debug"
    - index: "filebeat-jay-err-%{[beat.version]}-%{+yyyy.MM.dd}"

How are you adding new content to the log file?
