Hi all,

I would like to know if it is possible to use the same 
provider:tracepoint probe in several processes, without getting 
following error :

LTTng-UST: Error (-17) while registering tracepoint probe. Duplicate 
registration of tracepoint probes having the same name is not allowed.
Aborted (core dumped)

And how to do it ?

Franck

Yes, it is possible, but they need to have _exactly_ the
same signature. (same parameters and fields).

Thanks,
