NAME

babeltrace2-sink.utils.counter - Babeltrace 2's message counter sink component class

DESCRIPTION

A Babeltrace 2 sink.utils.counter component prints to the standard output the number of messages it consumes with a count for each type.

            |                    +--> Statistics to the
Messages -->@ in                 |    standard output
            +--------------------+
 
See babeltrace2-intro(7) to learn more about the Babeltrace 2 project and its core concepts.
 
The component’s output looks like this:
 
        3842964 Event messages
              4 Stream beginning messages
              1 Stream end messages
             18 Packet beginning messages
             14 Packet end messages
            189 Discarded event messages
              0 Discarded packet messages
              3 Message iterator inactivity messages
        3843000 messages (TOTAL)
 
By default, a sink.utils.counter component prints a new block of statistics every 1000 consumed messages, whatever their types. You can use the step parameter to override this default period.
 
The component always prints a block of statistics when there’s no more messages to consume from its upstream message iterator and the last block was different.
 
By default, a sink.utils.counter component prints the count of messages for each type, even if this count is 0. You can make it hide the zero counts with the hide-zero parameter.

INITIALIZATION PARAMETERS

hide-zero=yes [optional boolean]
Do not print the statistics lines where the count is zero.
step=STEP [optional unsigned integer]
Print a new block of statistics every STEP consumed messages instead of 1000.
 
If STEP is 0, then the component only prints statistics when there’s no more messages to consume.
