Overview

This check monitors an Nvidia Jetson board. It reports the metrics collected from tegrastats.

Setup

Installation

The Nvidia Jetson check is included in the Datadog Agent package. No additional installation is needed on your server.

Configuration

  1. Create a jetson.d/conf.yaml file in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your Jetson performance data. See the sample jetson.d/conf.yaml.example for all available configuration options.

  2. Restart the Agent.

Validation

Run the Agent’s status subcommand and look for jetson under the Checks section.
