How to use NVIDIA System Profiler (L4T) on NX?

I’d like to proflile my program on NX. Although I saw the web: NVIDIA Nsight Systems | NVIDIA Developer, I can not find the tool running on host( such as ubunut 18.04).
Is the tool in JetPack? However, the jetpack is an image… How can I install the tool on the host PC?
Thanks!
