Good catch Philippe,
I pushed a commit that enforces validation of event class/instance
prototypes (TP_ARGS()) at compile-time.
It is pushed into lttng-ust master as:
commit c75c0422c64f33c0102e1778cecc812c58b700e5

Fix: check
In `resolution_management_tp.tp`, can you try using the exact same
`TP_ARGS` content for both `TRACEPOINT_EVENT_INSTANCE` (also matching
the `TP_ARGS` content of `TRACEPOINT_EVENT_CLASS`)? It's the only
difference I can see.

I am really struggling trying to get user space tracing working predictably and
consistently and would appreciate some help.
I created a trace event called
kvm_server:new_connection_tracepoint (see attached), I then use lttng-gen-tp to
generate the .c and .h files which I link to the program a

Please clarify: no, there will be several root user-space lttng-consumerd
daemons or no, there will be just one root user-space lttng-consu

I ran a little experiment whose results surprised me. Using a non-tracing
group user account, I first made sure I had a root lttng-sessiond running and a
user-space lttng-sessiond. In the first I set up a trace for some kernel
events plus all user-space events. In the second I set up a tra

Hi,
In your example, you are running the tracer as root (with "sudo") but
your application is run by your own user. Somebody correct me if I'm
wrong, but I assume that in a case like this the root tracer will not
see the other user's applications.
Could you try running the lttng commands without
