hello
i am using tegrastats program to know CPU & GPU utilization.
i don’t know exact information about tegrastats.
CPU% and GPU% are utilization exactly? i hope that

Hi gooooooo,

Please take a look at “Appendix”->“Tegra Stats Utility” section in https://developer.nvidia.com/embedded/dlc/l4t-documentation-24-2-1 first. Thanks!

thank you, vickyy.
in Tegra Stats Utility, CPU[x%] is Load statistics.
but, i see “This is a rough approximation based on time spent in system idle process as reported by the Linux kernel in /proc/stat file.”
typically CPU utillization is caculated through /proc/stat information.
then… in this point, Utilization = load ???

Yes!

Hi Vicky, I checked the appendix, but found no guide on tegrastats showing memory usage for specific Linux process? nvidia-smi can show such information as follow

NVML doesn’t support JTX1 so nvidia-smi isn’t available.
Please take a look at [url]NVML API Reference Guide :: GPU Deployment and Management Documentation.
