[lttng-dev] Hooking up callbacks to LTTng USDT Events

Hi everyone,

Hope you're all good. 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.

Thanks!

Hi Adel,

It sounds to me like the feature you might want to try and use is the 
combining triggers with the user space application notification action.

C.f. https://lttng.org/docs/v2.13/#doc-trigger

thanks,
