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,
