At least userspace tracing seems to work. I would recommended, again, that you first try tracing on a dummy application, a really simple one. Then move to the usage of cyg_profile on that dummy app then to your application. The cyg profile events are the following: lttng_ust_cyg_profile_fast:func_entry lttng_ust_cyg_profile_fast:func_exit and, when using liblttng-ust-cyg-profile.so: lttng_ust_cyg_profile:func_entry lttng_ust_cyg_profile:func_exit I would recommend that you first start grep-ing (lttng_ust_cyg) for this in the trace to see if any is getting hit and recorded. If it is not the case, take a step back try with a dummy app and if nothing works with the dummy app we can at least try to help you from there and remove all other variable since you will be able to share the dummy app with us.
