I am trying to profile my AGX Drive Xavier application where I would like to monitor the GPU and DLA overheads for performance.

I could not locate nsys or any Nsight related libraries under /usr/local/cuda-/*

From what I understand to generate a nsys profile I would need to do the following:
trtexec --onnx=foo.onnx --profilingVerbosity=detailed --saveEngine=foo.plan
nsys profile -o foo_profile trtexec --loadEngine=foo.plan --warmUp=0 --duration=0 --iterations=50

Is the 2nd step run on Host processor instead of AGX?


Hi, @user3705
Please find it under /opt/nvidia/nsight-systems and refer to Nsight Systems User Guide :: Nsight Systems Documentation. Thanks.


I do not see nsight-systems under /opt/nvidia/
Do I need to enable something when installing using SDK? or is this a separate installation?

I believe it is part of host components installed with DRIVE OS 5.2.6 by SDK Manager.
Did you check on your host system installed with the host components?

This should be your installation log.


Yes, nsys-ui it is installed on the host. I don’t see the nsys CLI.
