Babeltrace 2's common graph utilities plugin


The Babeltrace 2 utils plugin contains common, generic utility component classes which you can use in any processing graph.

See babeltrace2-intro(7) to learn more about the Babeltrace 2 project and its core concepts.

Component Classes


Muxes messages by time.

See babeltrace2-filter.utils.muxer(7).


Discards all the consumed messages with a time outside a given time range, effectively “cutting” trace streams.

See babeltrace2-filter.utils.trimmer(7).


Prints the number of consumed messages, either once at the end or periodically.

See babeltrace2-sink.utils.counter(7).


Consumes messages and discards them (does nothing with them).

This is useful for testing and benchmarking a trace processing graph application, for example.

See babeltrace2-sink.utils.dummy(7).


If you encounter any issue or usability problem, please report it on the Babeltrace bug tracker (see <>).


The Babeltrace project shares some communication channels with the LTTng project (see <>).


The Babeltrace 2 project is the result of hard work by many regular developers and occasional contributors.

The current project maintainer is Jérémie Galarneau <>.
