# babeltrace2-plugin-utils(7)

Babeltrace 2: Common graph utilities plugin

## NAME

babeltrace2-plugin-utils - Babeltrace 2: Common graph utilities plugin

## DESCRIPTION

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

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

## COMPONENT CLASSES

**filter.utils.muxer**

Muxes messages by time.

See [**babeltrace2-filter.utils.muxer**(7)](/babeltrace2-filter.utils.muxer/7.md).

**filter.utils.trimmer**

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

See [**babeltrace2-filter.utils.trimmer**(7)](/babeltrace2-filter.utils.trimmer/7.md).

**sink.utils.counter**

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

See [**babeltrace2-sink.utils.counter**(7)](/babeltrace2-sink.utils.counter/7.md).

**sink.utils.dummy**

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)](/babeltrace2-sink.utils.dummy/7.md).
