[Serial logs]
    ## Example: Log collector that will collect logs from a serial interface.

    ## Required settings
    enabled = no
    log type = flb_serial

    ## Optional settings, common to all log source. 
    ## Uncomment to override global equivalents in netdata.conf.
    # update every = 1
    # update timeout = 10
    # use log timestamp = auto
    # circular buffer max size MiB = 64
    # circular buffer drop logs if full = no
    # compression acceleration = 1
    # db mode = none
    # circular buffer flush to db = 6
    # disk space limit MiB = 500

    ## Set up configuration specific to flb_serial
    log path = /dev/pts/4
    bitrate = 115200
    min bytes = 1
    # separator = X
    # format = json

    ## Submit structured log entries to the system journal
	# submit logs to system journal = no

    ## Charts to enable
    # collected logs total chart enable = no
    # collected logs rate chart enable = yes

    ## Example of extracting custom metrics from serial interface messages:
    # custom 1 chart = UART0
    # # custom 1 regex name = test
    # custom 1 regex = .*\bUART0\b.*
    # # custom 1 ignore case = no
