Hey all, when I trace with perf, I can see page_faults occurring. But when I do something like the following with lttng:
lttng create lttng enable-channel kernel -k lttng enable-event -c kernel -k -a lttng start # trigger page faults lttng stop then I do not see any page faults in tracecompass/babeltrace. What do I need to do to see those too? I'm aware that lttng comes with its own set of tracepoints - i.e. it's not using the same tracepoints that perf knows about. But googling shows me e.g. this: https://lists.lttng.org/pipermail/lttng-dev/2013-April/019954.html https://lists.lttng.org/pipermail/lttng-dev/2016-May/026033.html Which sounds like the feature should be available in lttng too? I'm using the ArchLinux packages in AUR, i.e. version 2.9.2 of LTTng and kernel 4.10.13-1.
