Here is a youtube video showing how userspace and kernel traces can play nicely together.

This video is a helper on that front. Experiments are a collection of traces that have similarities and thus can have enhanced analyses as their information paints a full picture. Some examples of where experiments shine: * Resources Views ... www.youtube.com ________________________________ From: lttng-dev <lttng-dev-boun...@lists.lttng.org> on behalf of Matthew Khouzam via lttng-dev <lttng-dev@lists.lttng.org> Sent: Wednesday, August 23, 2023 11:28 AM To: lttng-dev@lists.lttng.org <lttng-dev@lists.lttng.org>; Bala Gundeboina <bala.gundebo...@kpit.com> Subject: Re: [lttng-dev] userspace logs cpu analysis and LTTng UST Callstack I believe Percepio Tracealyzer is a fine commercial product, I have spoken to the CEO, he seems like a great guy. I cannot speak for his work, however, with eclipse trace compass, I want to make sure you know, with an experiement you can mix userspace and kernel traces. Then the userspace events complement the kernel views. ________________________________ From: lttng-dev <lttng-dev-boun...@lists.lttng.org> on behalf of Bala Gundeboina via lttng-dev <lttng-dev@lists.lttng.org> Sent: Wednesday, August 23, 2023 2:17 AM To: lttng-dev@lists.lttng.org <lttng-dev@lists.lttng.org> Subject: [lttng-dev] userspace logs cpu analysis and LTTng UST Callstack Hi all, I have capturing kernel and userspace trace logs with LTTng but kernel logs will give more useful information but userspace logs is not giving more useful information compared to kernel trace logs, how to get the more data from userspace trace logs. PFA of userspace and kernel screenshots if you observe the kernel screenshot we will get per core cpu usage, thread analysis and more . i am not able to load userspace trace logs in tracealyzer ,is tracealyzer is not supported the userspace logs ? , is there anyway we can make enable it ? kindly please me to sort out of this problem.
