Hi,
I hope someone can help me here, because I am gradually becoming desperate to get this running.
I am using a ThirdParty library, everything works well but when deploying for HoloLens performance gets really bad and i started to track down the issue.
This led me to Unreal Insights, a very powerful tool, also suitable for in-depth analyses for my PhD 
Then i found the folder Runtime/Tracelog containing some standalone-named files and create_standalone.py for creating a single-header library trace.h.
I included trace.h to my ThirdParty library build (needed some modifications as it was not useable just after generating by the python script) and with some more work i managed it to get at least a event entry in the Unreal Insights trace, triggered from the third party library. But Counts and Timings are zero and still missing.
I could not found any documentation, so any hint how the output ofcreate_standalone.py is intended to use? Or I`m completely on the wrong track?
Thanks!
