主机网络接口流量监控

监控Linux主机网卡eth0流量: net_stream.sh

#!/bin/bash

in_pre=$(cat /proc/net/dev | grep eth0 | sed 's/eth0://g' | awk '{print $1}')
ot_pre=$(cat /proc/net/dev | grep eth0 | sed 's/eth0://g' | awk '{print $9}')

while [ true ]; do
        in=$(cat /proc/net/dev | grep eth0 | sed 's/eth0://g' | awk '{print $1}')
        ot=$(cat /proc/net/dev | grep eth0 | sed 's/eth0://g' | awk '{print $9}')
        diff_in=$((in-in_pre))
        diff_ot=$((ot-ot_pre))
        printf "eth0 in: %8s(KB/s)  out: %8s(KB/s)\n" $((diff_in/1024)) $((diff_ot/1024))
        in_pre=$((in))
        ot_pre=$((ot))
        sleep 1
done
