Hi I am new to tracing in Linux and to lttng. I have a multi-threaded user application and I want to see:
1) When the threads are scheduled to run 2) Which cores the threads are running on. I have installed lttng on Ubuntu 14.04 LTS. I am expecting to visualise the trace using TraceCompass. I have read the following doc section: http://lttng.org/docs/#doc-tracing-your-own-user-application In order to collect my trace, must I define custom tracepoint definitions ( in a tracepoint provider header file ), and insert tracepoints into my user application, or is there a simpler way of achieving my goal? Best regards David
