I'm working on something where I need to set up routines or callbacks for specific LTTng USDT events (sticking to user space, not kernel). The plan is to catch these events as they happen to spot performance issues. If anyone's done something like this or has pointers on how to pull it off, I'd really appreciate your advice.
