Thanks for your detailed responses :)
Actually i will begin by taking my own trace that i will configure it in
advance ( same event type , and i will add the different event context that
i need ) .
It's my first time to develop with python and i don't really know the
architecture of babeltrace , So can you help me and tell me how to proceed
to filter my data from CTF to the output Format that i will choose ?
