filebeat:
  prospectors:
    -
      paths:
        - /var/log/messages
      input_type: log
      document_type: syslog

    -
      paths:
        - //var/lib/docker/containers/*/*-json.log
      input_type: log
      document_type: containerlog
  registry_file: /var/lib/filebeat/registry
 
output:
  elasticsearch:
    hosts: ["10.10.20.203:9200"]
