      ### Multiline options
    
      # Multiline can be used for log messages spanning multiple lines. This is common
      # for Java Stack Traces or C-Line Continuation
    
      # The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
      #multiline.pattern: ^\[
    
      # Defines if the pattern set under pattern should be negated or not. Default is false.
      #multiline.negate: false
    
      # Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
      # that was (not) matched before or after or as long as a pattern is not matched based on negate.
      # Note: After is the equivalent to previous and before is the equivalent to to next in Logstash
      #multiline.match: after
    
      # The maximum number of lines that are combined to one event.
      # In case there are more the max_lines the additional lines are discarded.
      # Default is 500
      #multiline.max_lines: 500
    
      # After the defined timeout, an multiline event is sent even if no new pattern was found to start a new event
      # Default is 5s.
      #multiline.timeout: 5s
    
      # To aggregate constant number of lines into a single event use the count mode of multiline.
      #multiline.type: count
    
      # The number of lines to aggregate into a single event.

      #multiline.skip_newline: false
    
      # Setting tail_files to true means filebeat starts reading new files at the end
      # instead of the beginning. If this is used in combination with log rotation
      # this can mean that the first entries of a new file are skipped.
      #tail_files: false
    
      # The Ingest Node pipeline ID associated with this input. If this is set, it
      # overwrites the pipeline option from the Elasticsearch output.

      #symlinks: false
    
      # Backoff values define how aggressively filebeat crawls new files for updates
      # The default values can be used in most cases. Backoff defines how long it is waited
      # to check a file again after EOF is reached. Default is 1s which means the file
      # is checked every second if new lines were added. This leads to a near real time crawling.
      # Every time a new line appears, backoff is reset to the initial value.
      #backoff: 1s
    
      # Max backoff defines what the maximum backoff time is. After having backed off multiple times
      # from checking the files, the waiting time will never exceed max_backoff independent of the
      # backoff factor. Having it set to 10s means in the worst case a new line can be added to a log
      # file after having backed off multiple times, it takes a maximum of 10s to read the new line
      #max_backoff: 10s
    
      # The backoff factor defines how fast the algorithm backs off. The bigger the backoff factor,
      # the faster the max_backoff value is reached. If this value is set to 1, no backoff will happen.
      # The backoff value will be multiplied each time with the backoff_factor until max_backoff is reached

    # ================================= Processors =================================
    
    # Processors are used to reduce the number of fields in the exported event or to
    # enhance the event with external metadata. This section defines a list of
    # processors that are applied one by one and the first one receives the initial
    # event:
    #
    #   event -> filter1 -> event1 -> filter2 ->event2 ...
    #
    # The supported processors are drop_fields, drop_event, include_fields,
    # decode_json_fields, and add_cloud_metadata.
    #
    # For example, you can use the following processors to keep the fields that
    # contain CPU load percentages, but remove the fields that contain CPU ticks
    # values:
    #
    #processors:
    #  - include_fields:
    #      fields: ["cpu"]
    #  - drop_fields:
    #      fields: ["cpu.user", "cpu.system"]
    #
    # The following example drops the events that have the HTTP response code 200:
    #
    #processors:
    #  - drop_event:
    #      when:
    #        equals:
    #          http.code: 200
    #
    # The following example renames the field a to b:
    #
    #processors:
    #  - rename:
    #      fields:
    #        - from: "a"
    #          to: "b"
    #
    # The following example tokenizes the string into fields:
    #
    #processors:
    #  - dissect:
    #      tokenizer: "%{key1} - %{key2}"
    #      field: "message"
    #      target_prefix: "dissect"
    #
    # The following example enriches each event with metadata from the cloud
    # provider about the host machine. It works on EC2, GCE, DigitalOcean,
    # Tencent Cloud, and Alibaba Cloud.
    #
    #processors:
    #  - add_cloud_metadata: ~

    # The following example enriches each event with the machine's local time zone
    # offset from UTC.
    #
    #processors:
    #  - add_locale:
    #      format: offset

    #      #  key:                   "/etc/pki/client/cert.key"
    #
    # The following example enriches each event with docker metadata, it matches
    # container id from log path available in `source` field (by default it expects
    # it to be /var/lib/docker/containers/*/*.log).
    #
    #processors:

    # The following example enriches each event with host metadata.
    #
