Hi all,
I'm just getting started with lttng and have a couple of questions. My target
is getting userspace tracepoints to work in a c++ application I control. I
don't need kernel or system tracing. The target is running in a docker
container I have control over as well. Running with --privilege

I got this one figured out. I used strace -fp -trace=connect on the
target app to see why the connect was failing and it turns out there was a
mismatch between sessiond's apps-socket paths and libust's.
time to review my build environment I guess. It's very possible my docker
container's path
you can use an ftrace-enabled kernel with lttng (maybe even just tracecompass)
or perfetto to get that kind of trace
