我看了下，linux下的/proc/net/dev记录了每块网卡发送和接受的包和字节数。因此萌生想法，写了一个。运行效果： 复制代码 代码如下: [root@74-82-173-217 ~]# ./net.sh Current Ip: inet addr:74.82.173.217 Bcast:74.82.173.223 Mask:255.255.255.224 Summry info: RX bytes:203692709 (194.2 MiB) TX bytes:93525930 (89.1 MiB) eth0 Receive Bytes: 573 Packets: 3 eth0 Send Bytes: 3086 Packets: 3 eth0 Receive Bytes: 378 Packets: 7 eth0 Send Bytes: 11236 Packets: 7 eth0 Receive Bytes: 324 Packets: 6 eth0 Send Bytes: 444 Packets: 2 eth0 Receive Bytes: 54 Packets: 1 eth0 Send Bytes: 0 Packets: 0 具体脚本的内容如下，几乎不需要修改，就可以拿到任何机器上去使用了。 复制代码 代码如下: [root@74-82-173-217 ~]# cat net.sh #! /bin/bash #Author: Vogts WangTao 2008-12-18 #Get summry info echo "Current Ip: "`/sbin/ifconfig eth0 | grep inet` echo "Summry info: "`/sbin/ifconfig eth0 | grep bytes` #sleep 1 second ,monitor eth0 while true do receive1=`cat /proc/net/dev|grep eth0 | awk '{print$1}'|sed -s 's/eth0://g'` receive_pack1=`cat /proc/net/dev|grep eth0 | awk '{print$2}'` send1=`cat /proc/net/dev|grep eth0 | awk '{print$9}'` send_pack1=`cat /proc/net/dev|grep eth0 | awk '{print$10}'` sleep 1 receive2=`cat /proc/net/dev|grep eth0 | awk '{print$1}'|sed -s 's/eth0://g'` receive_pack2=`cat /proc/net/dev|grep eth0 | awk '{print$2}'` receive_cnt=`expr $receive2 - $receive1` receive_pack_cnt=`expr $receive_pack2 - $receive_pack1` send2=`cat /proc/net/dev|grep eth0 | awk '{print$9}'` send_pack2=`cat /proc/net/dev|grep eth0 | awk '{print$10}'` send_cnt=`expr $send2 - $send1` send_pack_cnt=`expr $send_pack2 - $send_pack1` echo 'eth0 Receive Bytes:' $receive_cnt ' Packets:' $receive_pack_cnt echo 'eth0 Send Bytes:' $send_cnt ' Packets:' $send_pack_cnt done |
