| 9 | babeltrace2-plugin-utils - Babeltrace's utilities plugin |
| 10 | |
| 11 | |
| 12 | DESCRIPTION |
| 13 | ----------- |
| 14 | The Babeltrace `utils` plugin contains common, generic utility component |
| 15 | classes which you can use in any processing graph. |
| 16 | |
| 17 | See man:babeltrace2-intro(7) to learn more about the Babeltrace |
| 18 | project and its core concepts. |

| 21 | COMPONENT CLASSES |
| 22 | ----------------- |
| 23 | compcls:filter.utils.muxer:: |
| 24 | Multiplexes the notifications received on its multiple input ports |
| 25 | by time to its single output port. |
| 26 | + |
| 27 | See man:babeltrace2-filter.utils.muxer(7). |
| 28 | |
| 29 | compcls:filter.utils.trimmer:: |
| 30 | Discards all the received events with a timestamp less than a given |
| 31 | beginning timestamp and greater than a given end timestamp, |
| 32 | effectively ``cutting'' the traces. |
| 33 | + |
| 34 | See man:babeltrace2-filter.utils.trimmer(7). |
| 35 | |
| 36 | compcls:sink.utils.dummy:: |
| 37 | Receives the notifications from its single input port and discards |
| 38 | them (does absolutely nothing with them). This is useful for |
| 39 | testing and benchmarking a trace processing graph application, |
| 40 | for example man:babeltrace2(1). |
| 41 | + |
| 42 | See man:babeltrace2-sink.utils.dummy(7). |
| 43 | |
| 44 | compcls:sink.utils.counter:: |
| 45 | Prints the number of notifications received from its single input |
| 46 | port, either once at the end or periodically. |
| 47 | + |
| 48 | See man:babeltrace2-sink.utils.counter(7). |
