Blank console output when profiling (nsight systems 2020.4.3)


Nothing shows up in the console window during profiling.


Can you give me the command line you were using to run?

I am using UI version connected to ‘localhost’ profiling target. Everything seems to work fine, application runs, samples are collected and the result is shown after application completes. It’s just there’s no any console output (though the new console window opens when you start profiling) and you can’t judge how far application is until completion.

Same happens on Linux (Centos 7).

Bumping up this post. Issue still persist.

Edit: in version 2021.1.1


This is a known issue. Nsight Systems for Windows is collecting the target application’s output to the std streams and stores it inside the resulting QDREP file.
You can see the output when you open the report in the nsys-ui host application, and select Files from the report sections droplist.
See example in the screenshot below.
