Hiļ¼dear
</p>
<p>
<br>
</p>
<p>
Hello, I have encountered some problems in using LTTNG, which is briefly described as follows. I am eager to get your help.
</p>
<p>
<br>
About the use of the untrack command.It is reproduced as follows:
</p>
<p>
I type the following commands in turn to start LTTNG, and set up not to monitor a particular process.(For example, I input the "top" command in the terminal, the PID of the "top" process is 72598, now I want LTTNG not to monitor the "top" process)
</p>
<p>
<br>
</p>
<ol>
<li>
lttng create my-kernel-session --output=/tmp/my-kernel-trace
</li>
<li>
lttng add-context -k -t pid
</li>
<li>
<span style="white-space:normal;">lttng add-context -k -t tid</span>
</li>
<li>
lttng enable-event --kernel --all
</li>
<li>
lttng untrack --kernel --pid=72598
</li>
<li>
lttng start
</li>
<li>
lttng destroy
</li>
<li>
babeltrace2 /tmp/my-kernel-trace > babeltrace.txt
</li>
</ol>
<p>
<br>
</p>
<p>
Unfortunately, the output still contains the data for PID72598.<br>
Even after I changed "lttng untrack --kernel -- PID =72598" to "LTTNG untrack-u -- PID =72598", this phenomenon still occurred.<br>
<br>
How do I use the lttng-untrack command to achieve my goal?
</p>
<p>
<br>
</p>
<p>
Looking forward to your reply.<br>
thanks,<br>
