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. +--------------------+ | sink.utils.counter | | +--> 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.
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.
