Hi Vivek, In order to collect a trace you need to instrument your application with LTTng-UST tracepoints.
If you like to gather the syscalls for instance, you need to install the LTTng modules and start your session daemon as root. If you are still experiencing problem, please provide the commands you use and setup. Thanks!
