GSoC Project | Basic Support for Trace Compass

[Ravindra Kumar Meena]

Hi Sebastian,

I was exploring the documentation of LTTng and babeltrace and come to the
conclusion that LTTng already produces trace data in CTF format. Since
Trace Compass already supports CTF trace data. So, what I am thinking that
instead of converting trace data to CTF why don't we just directly produce
trace data in CTF using LTTng.
