babeltrace2-sink.utils.counter − Babeltrace 2's message counter sink component class
A Babeltrace 2 sink.utils.counter component prints to the standard output the number of messages it consumes with a count for each type.

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.
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.
