babeltrace-sink.utils.counter - Babeltrace's notification counter
sink component class
The Babeltrace sink.utils.counter component class, provided by the
babeltrace-plugin-utils(7) plugin, once instantiated, prints to the
standard output the number of notifications it receives on its input
port, with a count for each type.
The component’s output looks like this:
664891 events
12 stream beginnings
0 stream ends
93 packet beginnings
81 packet ends
0 inactivities
6 discarded events notifications
375378 known discarded events
2 discarded packets notifications
5 known discarded packets
1040455 notifications (TOTAL)
By default, a sink.utils.counter component prints a new block of
statistics every 1000 received notifications, 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 notifications to receive from its input port and the last block
was different.
By default, a sink.utils.counter component prints the count of
notifications for each type, even if this count is 0. You can make it
hide the zero counts with the hide-zero parameter.
The following parameters are optional.
hide-zero=yes (boolean)
Do not print the statistics lines where the count is zero.
step=STEP (integer)
Print a new block of statistics every STEP received notifications
instead of 1000. If STEP is 0, then the component only prints
statistics when there’s no more notifications to receive.
Input
in
Single input port from which the component receives the
notifications to count.
This component class has no objects to query.
