I am trying to monitor power consumption of jetson nano using TEGRASTATS.I want to know what exactly is shown in tegrastats specilly POM_5V_IN,POM_5V_GPU and POM_5V_CPU.I also want to know what Integrated power consumption monitoring tool is used on jetson nano. RAM 1698/3965MB (lfb 99x4MB) CPU [16…

Hi thohtdelta, Please refer to the details in [url] Welcome — Jetson Linux<br/>Developer Guide 34.1 documentation Thanks

<VDD_name> X/Y <VDD_name> is power consumption (mW) for certain module “name”'s rail. X is current value and Y is average value. This is same for POM_5V_name.

Thanks kayccc I tried to save the data from tegrastats and ended up saving the whole line. It will be helpful if i can only save the power and temperature,please tell me where do tegrastats take those values from(like a file?),if so tell me the path.

Hi thohtdelta, Install the strace package: apt install strace Output used files: strace tegrastats 2>&1 | grep openat | grep sys You will get something like that: … openat(AT_FDCWD, “/sys/bus/i2c/devices/6-0040/iio_device/rail_name_0”, O_RDONLY) = 4 openat(AT_FDCWD, “/sys/bus/i2c/devices/6-004…

That was helpful @fedormelexin , I also wanted to know one more thing https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2FAppendixTegraStats.html%23wwpID0E0SB0HA After checking this link i am still confused whether POM_5V_IN is the …

I do not know which option is correct. Supply 4 Amps at 5 Volts through the Barrel Jack connector is 5V*4A = 20 Watts (MAX). 13 watts seems to be acceptable consumption. With sufficient cooling, the runs for a long time should not affect the board.

Just an observation: Jetson Nano without any peripherals with full CPU (no GPU) load seems to consume aroung 4.5W. [image]

@nanom Could you please share what monitoring tool/setup do you use on your screenshot?

Not sure, but it might be jtop: [image] jtop 📊 Simple package for monitoring and control your NVIDIA Jetson [Orin, Xavier, Nano, TX] series - rbonghi/jetson_stats

POM_5V_IN measures the overall 5V input to the board, it represents the total power consumption. You don’t need to add POM_5V_GPU and POM_5V_CPU to it. The GPU/CPU rails are provided for extra reference.
