Generating trace files

[AnonimiAngels]

How can i generate the trace files on linux in a c++ program?

Hi! There are many tools that can help. What do you want to trace?

Simplest is to use uftrace. You can also use LTTng-UST, lttng-kernel allows knowing what happened on the OS level. You could use perf with ctf bindings and intelpt if you have some difficult requirements. Really the core of the question is what do you want to trace, what do you want to visualize?

UFTrace, custom tracer, such as uprofiler or microprofiler or lttng-ust are your best bets, keep us informed on how it's going!
