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 ?
