(Simply) print netdev statistics

pnstat

pnstat prints netdev statistics. pnstat usage is simple and it is designed for (my) network-related experiments.

$ ./pnstat -h
usage: pnstat [-h] [-n NETDEV] [-i INTERVAL] [-c COUNT] [-o OUTPUT] [-j]
              [-k {default,witherrors,all}] [--per-second]

(Simply) print netdev statistics

options:
  -h, --help            show this help message and exit
  -n NETDEV, --netdev NETDEV
                        target netdev(s) (default all netdevs)
  -i INTERVAL, --interval INTERVAL
                        interval
  -c COUNT, --count COUNT
                        count (default infinite)
  -o OUTPUT, --output OUTPUT
                        output file (default stdout)
  -j, --json            output as jsonl
  -k {default,witherrors,all}, --keys {default,witherrors,all}
                        keys to be gathered
  --per-second          print values in per-second basis
