This project is a Grafana dashboard, driven by a Prometheus metrics collector, for monitoring NVIDIA Jetson devices [Xavier NX, Nano, AGX Xavier, TX1, TX2] operating autonomously in a headless fashion (i.e. no connected display and associated user-input devices).

The following hardware and software should already be configured and operational:

• NVIDIA Jetson device
• A host running Grafana
• A host running Prometheus

1. Ensure jetson_stats is installed on your Jetson device. Full instructions can be found on the project GitHub repo

2. Next, install the Prometheus metrics collector

   nvidia@agx-desktop $ pip install prometheus-client
   nvidia@agx-desktop $ sudo cp jetson_stats_prometheus_collector.py /usr/local/bin/

3. Install the Prometheus metrics collector as a system background systemd service

   nvidia@agx-desktop $ sudo cp jetson_stats_prometheus_collector.service /etc/systemd/system/
   nvidia@agx-desktop $ sudo systemctl daemon-reload
   nvidia@agx-desktop $ sudo systemctl start jetson_stats_prometheus_collector
   nvidia@agx-desktop $ sudo systemctl status jetson_stats_prometheus_collector

   Alternatively, you can install the systemd service for the current user as shown below:

   nvidia@agx-desktop $ mkdir -p ~/.config/systemd/user
   nvidia@agx-desktop $ sudo cp jetson_stats_prometheus_collector.service /etc/systemd/system/
   nvidia@agx-desktop $ systemctl --user daemon-reload 
   nvidia@agx-desktop $ systemctl --user start jetson_stats_prometheus_collector
   nvidia@agx-desktop $ systemctl --user status jetson_stats_prometheus_collector

Note: The Prometheus metrics collector listens on port 8000 by default. If you wish to change this you will need to edit the jetson_stats_prometheus_collector.service file and change the --port argument to your required port number. You will also need to ensure to use the same port value later in this readme when referencing REPLACEME_YOUR_JETSON_PROMETHEUS_COLLECTOR_PORT.

1. Install required Grafana plugins and restart the Grafana service

   $ grafana-cli plugins install marcusolsson-dynamictext-panel
   $ sudo systemctl restart grafana-server.service

1. Open the Prometheus config:

   $ sudo nano /etc/prometheus/prometheus.yml

2. Add metrics collection job config for the Jetson device

   scrape_configs:
     - job_name: 'nvidia_jetson'
       static_configs:
       - targets: ['REPLACEME_YOUR_JETSON_HOST_IP:REPLACEME_YOUR_JETSON_PROMETHEUS_COLLECTOR_PORT']

   Note: Replace the REPLACEME_XX parts with the corresponding values.

3. Restart the Prometheus service for the changes to take effect

   $ sudo systemctl restart /etc/systemd/system/prometheus.service

1. From the Grafana Admin Dashboard select +Create -> Import

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

3. Next, copy and paste the contents of modified jetson_stats_grafana_dashboard.json into the text box named Import via panel json or select the file using the Upload JSON file button

4. The jetson-stats-grafana-dashboard should now be available
