 I tried tracing example given here
https://lttng.org/docs/v2.10/#doc-tracing-your-own-user-application. This
example generates the CTF data. I have attached all the files in case if
you want to try them out. After that, I used babeltrace to read the CTF
data and print it in text format. I have also attached the
output("babeltrace CTF.png") of the command line.

I used "babeltrace ~/lttng-traces/my-user-space-session*" command line to
read the CTF data.
