NVIDIA Jetson Xavier - Evaluating Performance
tegrastats
The Jetpack provides the tegrastats utility, which reports memory usage and processor usage for Tegra-based devices.
This utility in the NVIDIA user home directory and can be run using the command:
sudo ./tegrastats
tegrastats supports the following command-line options.
--interval <int> The interval at which tegrastats is to write output to the log, in milliseconds. The default interval is 1000 msec. --verbose Print verbose messages. --stop Stop any running instances of tegrastats. --logfile <out_file> Dump the output of tegrastats to <out_file>.
