    # https://github.com/open-telemetry/opentelemetry-log-collection/blob/main/docs/operators/recombine.md
    # By the time of reconstructing a multiline log the following information is available to

    # identifier has to be specified in for each multiline config.
    # The following example shows how to setup multiline log processing for logs having subsequent
    # log lines written with an offset. Let's say a k8s deployment called "buttercup-app" is
    # scheduled to run in "default" namespace with a java container called "server", and the

    # ```
    #
    # For `file` logs, `path` is required for specifying where is the log files. Log files are expected in `/var/log`, example:
    # ```
    # docker:
    #   from:
    #     file:
    #       path: /var/log/docker.log
    # ```
    #
    # For `container` logs, `pod` field is required. It represents part of
    # the pod name, can be name of a deployment or replica set. Use "*" to
    # apply the configuration to all pods. Optional `container` value can be
    # used to apply configuration to a particular container.
    # ```
    # kube-apiserver:
    #   from:
    #     pod: kube-apiserver

    #     container: etcd-container
    # ```
    #
    # = timestamp =
    # `timestampExtraction` defines how to extract timestamp from logs. This *only* works for `file` source.
    # To use `timestampExtraction` you need to define both:
    # - `regexp`: the Regular Expression used to find the timestamp from a log entry.
    #             The timestamp part must be in a `time` named group. E.g.
    #             (?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2})
    # - `format`: a format string defintes how to parse the timestamp, e.g. "%Y-%m-%d %H:%M:%S".
    #             More details can be find: http://ruby-doc.org/stdlib-2.5.0/libdoc/time/rdoc/Time.html#method-c-strptime
    #
    # = multiline =
    # `multiline` options provide basic multiline support. Two options:
    # - `firstline`: a Regular Expression used to detect the first line of a multiline log.
    # - `flushInterval`: The interval between data flushes, default value: 5s.
    #
    # = sourcetype =
    # sourcetype of each kind of log can be defined using the `sourcetype` field.
    # If `sourcetype` is not defined, `name` will be used.
    #
    # ---
    # Here we have some default timestampExtraction and multiline settings for kubernetes components.
    # So, usually you just need to redefine the source of those components if necessary.
