Hi,

I think you need to take a step back and figure out how lttng is deployed and more
importantly the overall architecture of lttng and its principal moving pieces.

First, you need a functioning and running lttng-sessiond process.

From lttng-console-log.txt:

   root@RocrLnx23:~/git/compute/out/ubuntu-18.04/18.04/bin#  lttng list -u
   Error: Unable to list UST events: No session daemon is available

The error is clear here, no lttng-sessiond is running or at least, the lttng CLI
cannot communicate with it.

Here the sessiond was killed before performing this operation based on
CmdSequence.txt. You seem to have forgot to start a lttng-sessiond before
performing the call to your application and `lttng` commands.

My previous email stated the following:
  With the app running and having the LD_PRELOAD correctly set, and a sessiond
  (sessiond should have read lttng-sessiond) running.

Then, if we look at kernel modules loading.

From lttng-sessiond.txt:

DEBUG1 - 19:50:34.293777619 [27093/27093]: libkmod: could not find module by name='lttng_ring_buffer_client_discard'
 (in log_kmod() at modprobe.c:108)
Error: Unable to load required module lttng-ring-buffer-client-discard
Warning: No kernel tracer available

libkmod expect the presence of lttng-modules kernel modules in: /lib/modules/$(uname -r)/

From lttng-system-env.txt:

  root@RocrLnx23:~# find /lib/modules/$(uname -r)/ | grep lttng

Yield nothing. I suspect that your modules are installed under:

  ~/git/compute/out/ubuntu-18.04/18.04/lib/modules/$(uname -r)/

Now, currently, lttng-sessiond when built with kmod support does not support
defining the modules locations (as far as I know) since we pass (NULL, NULL)
to the creation context (kmod_new). The default behaviour is to look into
/lib/modules/.... .

Albeit it would be nice to support such scenarios, this will not help you in the
short term. I would recommend the usage of symbolic link here to provide "/lib/modules/$(uname -r)/".

Note that this is overly complicated by the deployment scenario you are
currently using, which does not represent a typical deployment for most of our
users.

In any cases, again, this is only useful if you plan on doing kernel tracing. 

I would suggest that you might want to put effort in making sure Userspace
Tracing works.

Here I think the only thing missing is to have a running lttng-sessiond process
while you launch  ./rocminfo

Concretely:
    $ sudo -s
    # systemctl stop lttng-sessiond.service
    # pkill lttng-sessiond
    # cd ~/git/compute/out/ubuntu-18.04/18.04/lib
    # export LD_LIBRARY_PATH=`pwd`:$LD_LIBRARY_PATH
    # lttng-sessiond -vvv --verbose-consumer -b > /tmp/lttng-sessiond.log 2>&1
    # lttng create my_userspace_tracing_session
    # lttng enable-event -u -a
    # lttng start
    # LD_PRELOAD=liblttng-ust-cyg-profile-fast.so  LTTNG_UST_DEBUG=1     ./rocminfo
    # lttng destroy
    # babeltrace <the path trace as displayed after lttng create>
    # pkill lttng-sessiond


Note: here the manual starting and termination of lttng-sessiond is only for the
purpose of testing. In a normal deployment lttng-sessiond is a daemon.

Note that the sequence of `lttng` commands is important here since I expect
./rocminfo to not have a long lifetime. In other word, the `rocminfo` will have
finished and unregistered from lttng-sessiond perspective before you are able to
manually either list its tracepoints or setup a tracing session after you started
the application.

Please read the following and try to perform it under your deployment scenario:

https://lttng.org/docs/v2.12/#doc-tracing-your-own-user-application


Hope this helps.

Cheers
