BABELTRACE2-SINK.(7) Babeltrace 2 manual BABELTRACE2-SINK.(7)
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=VAL [optional boolean]
If VAL is true, then do not print the statistics lines where
the count is zero.
Default: false.
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.
