Dear @snow.yin ,
Tegrastars does not give memory statistics.
Does User Guide — Nsight Systems helps ?

could you please give more specific guide on this topic, like which cmd would collect the info we need?

Nsight may support GPU BW, but I did not see anything related to other cores.

I was expected something more clear and simple like below:

Dear @snow.yin ,
Using nsys, you can collected soc metrics. Please see User Guide — Nsight Systems.
The SoC metrics are listed at User Guide — Nsight Systems.

Also, please take a look at emc_log tool(EMC Log Utility — NVIDIA DriveOS 7.2.5 Linux SDK Early Access Developer Guide). It has list of clients and using stats parameter you can get bandwidth. Give a try and let us know your feedback.
