Comment on UPS input load
dieTasse@feddit.org 1 month agoAhaa, so what you are saying that me seeing the input load on UPS is not the cause of the measured power consumption but just a “symptom”. That something (be it TrueNAS/rpi/switch) really draws more. How can I do a thorough analysis of what the devices do? Normally I check logs and htop and see they are just chilling. I check cpu, i/o and network and I thought that it should be pretty good indicator of if something is happening. Especially when its 6 Watts more thats like whole another rpi 😀

I don’t think its rpi or network switch, unless you’ve overclocked rpi with liquid nitrogen 😅. So, I assume its TrueNas device.
If it were a significant power difference, say 20-30 watts, you could easily find the process using htop/iotop. However, 6 watt difference is a relatively small value for a device with ~25 watts of idle power . It might be a process using just 1% system resources. That’s why I would look for systemd timers, cronjobs etc. to find scheduled tasks on specific times. Another possibility is automated S.M.A.R.T. self-tests. Those tests don’t show up in htop or iotop.
