Linux下统计高速网络中的流量

netpps.sh统计每秒数据量，包含接收（RX）或发送（TX）

netpps.sh eth0

#!/bin/bash



INTERVAL="1"  # update interval in seconds



if [ -z "$1" ]; then

        echo

        echo usage: $0 [network-interface]

        echo

        echo e.g. $0 eth0

        echo

        echo shows packets-per-second

        exit

fi



IF=$1



while true

do

        R1=`cat /sys/class/net/$1/statistics/rx_packets`

        T1=`cat /sys/class/net/$1/statistics/tx_packets`

        sleep $INTERVAL

        R2=`cat /sys/class/net/$1/statistics/rx_packets`

        T2=`cat /sys/class/net/$1/statistics/tx_packets`

        TXPPS=`expr $T2 - $T1`

        RXPPS=`expr $R2 - $R1`

        echo "TX $1: $TXPPS pkts/s RX $1: $RXPPS pkts/s"

done

netspeed.sh描述网络传输中的接收（RX）发送(TX)带宽

netspeed.sh eth0

#!/bin/bash



INTERVAL="1"  # update interval in seconds



if [ -z "$1" ]; then

        echo

        echo usage: $0 [network-interface]

        T1=`cat /sys/class/net/$1/statistics/tx_bytes`

        sleep $INTERVAL

        R2=`cat /sys/class/net/$1/statistics/rx_bytes`

        T2=`cat /sys/class/net/$1/statistics/tx_bytes`

        TBPS=`expr $T2 - $T1`

        RBPS=`expr $R2 - $R1`

        TKBPS=`expr $TBPS / 1024`

        RKBPS=`expr $RBPS / 1024`

        echo "TX $1: $TKBPS kb/s RX $1: $RKBPS kb/s"
