I would love to look into the "lost event". Can you share the trace? maybe it's an easy win.</div>

<b>Subject:</b> How to show method entry/exit in Trace Compass?</font>
<div> </div>
</div>
<div>
<div dir="ltr">Hi<br>
<br>
I'm using LTTng 2.13.11 on Ubuntu 24.04 with Trace Compass 11.3.0 on Windows, to analyse a C++ app.
<div><br>
I have used LTTng and Trace Compass a little to instrument our user space app using lttng_ust_tracef(). I now want to show actual method entry/exit points in a Gantt type view.</div>
<div><br>
</div>
<div>With help from AI I instrumented entry/exit for one method. Babeltrace shows that the trace files contain those points:<br>
<br>
<time> sr1 myapp:method_entry: { cpu_id = 4 }, { class = "ThreadPool", method = "mainLoop" }</div>
<div><time> sr1 myapp:method_exit: { cpu_id = 6 }, { class = "ThreadPool", method = "mainLoop" }</div>
<div><br>
</div>
<div>But when I import the trace into Trace Compass I see the events but the trace shows only the app name, not the method name.<br>
<br>
What am I missing? Is there a user guide article that would help me?<br>
<br>
Best regards</div>
