[lttng-dev] lttng kernel events

[Jessica Foest]

Hi all,

Normally the following perf software event means the same thing :

page-faults OR faults
context-switches OR cs
cpu-migrations OR migrations

The questions is why both of them (the two representation of the event) are
presented in the context options of LTTng?

When i try to activate them when tracing the kernel activities no error
displayed, it means that both of them works fine.

is that normal ?

Regards

Yes, we support both the long forms and the shortcuts. Those may have the 
same meaning indeed. 

Thanks,
