[lttng-dev] Userspace Tracing

[Michael Steppe]

Hello!

I have a question regarding userspace tracing. I am working on a project on
which we have used LTTng in the past (prior to LTTng 2.0). In order to see
how our application was running in coordination with the kernel, we created
a .h file in which we would append strings to
"/mnt/debugfs/ltt/write_event" in order to see our application timing in
the LTTng viewer in Eclipse.

Since then we have updated to LTTng 2.0.4. It would be very hard for us to
change to a different version at the current time. I have noticed that
/mnt/debugfs/ltt/write_event no longer exists in 2.0.4 and was wondering
(crossing my fingers) that this location has simply changed or is there a
new filesystem that you use?

Thanks!!
