Yes, that is the expected behaviour, we work with packets (sub-buffers), so the smallest unit we can store is the subbuf-size. With 2.7.3 I get this warning when I try your command: Warning: Tracefile size rounded up from (8192) to subbuffer size (33554432) Julien _______________________________________________ lttng-dev mailing list lttng-dev@lists.lttng.org https://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
