Hi Layne,<br>
<br>
Thanks for your interest in those projects!<br>
<br>
The LTTng scope beta project was an attempt at doing a significant UX<br>
redesign of Trace Compass, starting from a use-cases/user workflow<br>
perspective. We currently don't have the resources/funding/staff to<br>
work on this project further, so it has not progressed for a while.<br>
<br>
You should look at the Trace Compass and VSCode trace extension<br>
projects instead, which have a lot more activity:<br>

<br>
<br>
The LTTng analyses beta project is a set of python scripts to analyze<br>
LTTng traces. Our original intent with that project was that EfficiOS<br>
would fund the work to create those analyses as prototypes in Python,<br>
and eventually customers would fund the rather large amount of work<br>
required to go from a prototype (slow scripts) to a production quality<br>
project (faster C++ implementation, generic state tracking module).<br>
Unfortunately, this never materialized, so this beta project has been<br>
on the back burner as well.<br>
<br>
In the recent years we have focused our efforts on the Babeltrace 2<br>
project and on CTF2 (Common Trace Format version 2).<br>
<br>
Feel free to have a look at Trace Compass and VSCode trace extension, and<br>
please let us know if LTTng scope and LTTng analyses fill a gap that is<br>
not covered by those other tools.<br>
<br>
Thanks,<br>
