Hi Jonathan
Glad to see your words again!

Yes,Step by step according to your cmd:
The session.log view attachments.there are some error as flow, I installed lttng-ust already:
lttng-consumerd: error while loading shared libraries: liblttng-ust-ctl.so.2: cannot open shared object file: No such file or directory
Error: Condition timed out. The consumer thread was never ready. Killing it
Error: Fatal error spawning consumer control thread

Ha. You know it? It's D02.
From name hope to see one in flesh some day.
>Does "lttng list -k" return a list of events ?
Yes.it works,list many event name
Then you have a live lttng-sessiond.

Yes ,I tried,reboot the board,and "ps -A|grep lttng" ,here is no lttng session.
after " lttng create mysession ",there is an error " Error: Could not get lock file /var/run/lttng/lttng-sessiond.lck, another instance is running."
I used "2.8.0-rc1" version this time. Same problem.
Logs:
-bash-4.3# ps -A|grep lttng
-bash-4.3# lttng create mysession
Spawning a session daemon
Session mysession created.
Traces will be written in /root/lttng-traces/mysession-19700101-015353
The following command "lttng-sessiond -vvv" will necessarily fail since the previous command " lttng create mysession" just spawned one.
Could you try these on a rebooted board as root:
(Make sure there is no sessiond running)
lttng-sessiond -vvv > sessiond.log 2>&1
lttng create
lttng enable-event -a -k
lttng start
sleep 1
lttng stop
lttng view
If on "lttng view" there is no events or any of the commands fail make sure to include their output and the sessiond.log file so we can pinpoint the problem.
