    # Daemon
    # ======
    # instruct Fluent Bit to run in foreground or background mode.
    daemon       Off

    # Log_Level
    # =========
    # Set the verbosity level of the service, values can be:
    #
    # - error
    # - warning
    # - info
    # - debug
    # - trace
    #
    # by default 'info' is set, that means it includes 'error' and 'warning'.

    # Parsers File
    # ============
    # specify an optional 'Parsers' configuration file
    parsers_file parsers.conf

    # Storage
    # =======
    # Fluent Bit can use memory and filesystem buffering based mechanisms
    #
    # - https://docs.fluentbit.io/manual/administration/buffering-and-storage
    #
    # storage metrics
    # ---------------
    # publish storage pipeline metrics in '/api/v1/storage'. The metrics are
    # exported only if the 'http_server' option is enabled.
    #
    storage.metrics on

    # storage.path
    # ------------
    # absolute file system path to store filesystem data buffers (chunks).
    #
    # storage.path /tmp/storage

    # storage.sync
    # ------------
    # configure the synchronization mode used to store the data into the
    # filesystem. It can take the values normal or full.
    #
    # storage.sync normal

    # storage.checksum
    # ----------------
    # enable the data integrity check when writing and reading data from the
    # filesystem. The storage layer uses the CRC32 algorithm.
    #
    # storage.checksum off

    # storage.backlog.mem_limit
    # -------------------------
    # if storage.path is set, Fluent Bit will look for data chunks that were
    # not delivered and are still in the storage layer, these are called
    # backlog data. This option configure a hint of maximum value of memory
    # to use when processing these records.
    #
    # storage.backlog.mem_limit 5M
