Surely the same can be done in user-space? Looking at /usr/src/lttng-ust/include/lttng/tracepoint.h, we see there are TRACEPOINT_EVENT_CLASS and TRACEPOINT_EVENT_INSTANCE macros right beside TRACEPOINT_EVENT, so I suspect you could replace your message.tp with something like: [...] TRACEPOINT_EVENT_CLASS( thorium_message, thorium_event_template, TP_ARGS( struct thorium_message *, message ), TP_FIELDS( ctf_integer(int, message_number, message->number) ctf_integer(int, message_action, message->action) ctf_integer(int, message_count, message->count) ctf_integer(int, message_source_actor, message->source_actor) ctf_integer(int, message_destination_actor, message->destination_actor) ctf_integer(int, message_source_node, message->source_node) ctf_integer(int, message_destination_node, message->destination_node) ) ) TRACEPOINT_EVENT_INSTANCE( thorium_message, thorium_event_template, actor_send, TP_ARGS( struct thorium_message *, message ) ) TRACEPOINT_EVENT_INSTANCE( thorium_message, thorium_event_template, node_send, TP_ARGS( struct thorium_message *, message ) ) [...] Try it and let us know. This should be added to the lttng-gen-tp man pages if it works. Daniel U.
