I found someone who complies netdata with nvidia-smi enabled and it doesn't work.
I presume because the nvidia-smi isn't installed in the default location.
I will have to look to where it's installed.
My telegraf says the same thing:
2019-03-10T04:12:10Z E! [inputs.nvidia_smi]: Error in plugin: nvidia-smi binary not at path /usr/bin/nvidia-smi, cannot gather GPU data
