Hi, I am currently tracing many processes with LTTng-UST on a system under heavy load, with 2 CPUs.
The traces seem to be missing ust-events near the end of a trace. After doing some analysis, it seems that events are missing from the other CPU then the process exits on. More concretely: During the lifetime of a process: - Process X executes on CPU 0,1: all events are in the trace Just before the process is about to exit: - Process X executes on CPU 0: missing events from the trace A few mili-seconds later: - Process X executes on CPU1 and exits: The last events are in the trace Is this behavior expected, or am I running into an LTTng-UST bug? And would there be any workaround? Kind regards, Rolf Theunissen _______________________________________________ lttng-dev mailing list lttng-dev@lists.lttng.org https://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
