The current LTTng Userspace Tracer backend does not build against modern
libraries. LTTng has changed the library ABI several times, making it
difficult to support this backend.
Due to lack of users, remove this trace backend until someone turns up
who is willing to actively maintain it.

Tracepoints were called Page Wait for LTT and buffer_wait_start
buffer_wait_end for LTTng 0.x.
Now I looked for the
Hi,
I am using backfire version of Openwrt and would like to try to use
profiling features bring by tools like lttng. I found some Makefile
packages on openwrt website to build lttng-tools and lttng-ust with
recent version of openwrt version but I am not able to compile lttng
without error.

Hi Stefan,
I am actually using LTTng 2.x as a backend for UST to do some
performance analysis and latency investigation using Qemu/KVM. I already
have all the patches ready to replace the old 0.x interface, and I am

for the consumer to be done? Does the session daemon force the consumer to
wrap up prematurely? (Assuming flight recorder mode, of
