nvidia-smi daemon help

Hello,
I cannot understand the use of nvidia-smi with the daemon mode.
How is it supposed to be used?
I can get a binary data file on /var/log/nvstats, then?

Thanks

If you run “man nvidia-smi”, and look at the “Replay Mode” section, you’ll see how to dump info from the daemon log.
