| 7 | NAME | |
| 8 | ---- | |
| 9 | babeltrace-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:babeltrace-intro(7) to learn more about the Babeltrace | |
| 18 | project and its core concepts. | |
| 19 | ||
| 20 | ||
| 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:babeltrace-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:babeltrace-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:babeltrace(1). | |
| 41 | + | |
| 42 | See man:babeltrace-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:babeltrace-sink.utils.counter(7). | |
