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). | |
