<body class='hmmessage'><div dir='ltr'>Thanks for your answer.<br><br>I tried to use the TRACEPOINT_LOGLEVEL macro, but I was not able to make it working. I have my macro immediately follow my TRACE_EVENT macro "TRACEPOINT_LOGLEVEL(hello_world,my_first_tracepoin<span style="background-color: rgb(255, 255, 255);">t,<span style="background-color: rgb(255, 255, 0);">TRACE_WARNING</span></span>)"<br><br>I enabled the event with the --loglevel <span style="background-color: rgb(255, 255, 255);"><span style="background-color: rgb(255, 255, 0);">TRACE_WARNING</span></span> parameter. When I run my code, and I do `lttng list --userspace`, I still get "hello_world:my_first_tracepoint (loglevel: <span style="background-color: rgb(255, 255, 0);">TRACE_DEBUG_LINE</span> (13)) (type: tracepoint)"<br><br>It looks like my code does not set the loglevel correctly, so it is still using the default loglevel. Am I doing anything wrong?

The document talked about it could assign a loglevel to each event.
