NVIDIA Jetson integration

Install the infrastructure agent

To use the NVIDIA Jetson integration, you need to first install the infrastructure agent onto your host. The infrastructure agent monitors the host itself, while the integration itself extends your monitoring to include NVIDIA Jetson-specific data.

Save tegrastats to a file

From your shell environment, change to the tegrastats directory and run this command to save NVIDIA Jetson metrics at 5 second intervals:

$
sudo tegrastats --interval 5000 --logfile tegrastats

Enable the NVIDIA Jetson integration with nri-flex

To set up the NVIDIA Jetson integration, follow these steps:

1. Create a file named nvidia-jetson-config.yml and save it in the integrations directory:

   bash

   Copy

   $
   sudo nano /etc/newrelic-infra/integrations.d/nvidia-jetson-config.yml

2. Enable the agent to capture data from NVIDIA Jetson by adding the following snippet to your nvidia-jetson-config.yml file:

   integrations:
     - name: nri-flex
       config:
         name: JestonMetrics
         apis:
           - event_type: tegrastats
