Hi Nathan,
Thank you for the prompt response. I have fixed the kernel tracing problem and
indeed your diagnosis was accurate.
I shall post the changes I made to solve the problem so that there is a
searchable record for people in a similar position using the Poky component of
the Yocto project
You can use the snapshot feature to start recording whenever you
witness a significant latency[1].
You can use the system() function to trigger a record from your app.
e.g. system(lttng snapshot record);

I hope it helps.
Francis

Hello Forum,
Now that I have got LTTng built, I have tried some preliminary tests.
Unfortunately the results are not quite as I expect.
I have used LTTng previously, although I did not perform the kernel
integration. Using Eclipse TFM I could see various processes in the Control
Flow tab.

Hello,
I am getting an error (mentioned in the subject) while starting an
application which I wanted to trace. I am using the following version of
LTTng. *lttng (LTTng Trace Control) 2.5.0 - Fumisterie*
I tried to look the web if some of them have previously faced this error
and found this one.
