  pre_config:
    root:
      level: 'DEBUG'
  loggers:
    - name: "rails"
      outputters:
        - gelf

  outputters:
    - type: GelfOutputter
      name: gelf
      gelf_server: "<graylog_server_name>"
      gelf_port: "<graylog_server_port>"
      # Optional - showing default values
      # facility: "gelf-rb"
      # host: "#{Socket.gethostname}"
      # max_chunk_size: 'LAN'
      # level: DEBUG
