Hi, why power usage is always 0?

System is running Ubuntu server LTS 18.04 with python 3.6 and running jtop from jetston_stats I do get a working jtop.

I went as far as adding a debug print in there to dump what is being pulled up and my initial review didnt spot anything missing but python isnt a strong point and the Xavier unit is a custom which may be adding to the confusion.

Debug: self._jetson.board = {'hardware': {'Model': 'Transport XCB', '699-level Part Number': '699-82888-0004-400 G.0', 'P-Number': 'p2888-0004', 'Module': 'NVIDIA Jetson AGX Xavier (32 GB ram)', 'SoC': 'tegra194', 'CUDA Arch BIN': '7.2', 'Serial Number': '0420319084239', 'L4T': '32.5.1', 'Jetpack': '4.5.1'},
'platform': {'Machine': 'aarch64', 'System': 'Linux', 'Distribution': 'Ubuntu 18.04 Bionic Beaver', 'Release': '4.9.201-32.5.0_C01571-19S00A00.001.img+e443483e8c+ge443483e8c9c', 'Python': '3.6.9'},
'libraries': {'CUDA': '10.2.89', 'OpenCV': '4.1.1', 'OpenCV-Cuda': False, 'cuDNN': '8.0.0.180', 'TensorRT': '7.1.3.0', 'VPI': '1.0.15', 'Vulkan': '1.2.70'}}

Error being seen is as follows

Traceback (most recent call last):
File "./jetson_stats_prometheus_collector.py", line 192, in
REGISTRY.register(CustomCollector())
File "/usr/local/lib/python3.6/dist-packages/prometheus_client/registry.py", line 40, in register

I'm unclear about what is required for step 2 of the Grafana Dashboard Panel setup instructions:

2. Open the file jetson_stats_grafana_dashboard.json and update the __inputs entry for the DS_MY_PROMETHEUS value and save the file

nvidia-jetson_rev1.json as downloaded from grafana.com contains:

  "__inputs": [
    {
      "name": "DS_MY_PROMETHEUS",
      "label": "Prometheus",
      "description": "",
      "type": "datasource",
      "pluginId": "prometheus",
      "pluginName": "Prometheus"
    }
  ],

What should that look like after step 2, "update the __inputs entry"?
