Sometimes we need a more real-time view of the network card traffic on the server, here I wrote two small scripts, one with the shell (first write, only one network card can be viewed at a time), the other with Python (after the write, one can view multiple network cards). The script uses a while true "dead loop", every 10s from "/proc/net/dev" to take a value and calculates the average bandwidth within 10s
