使用nicstat查看网卡状态

我以前用脚本实现对实时网卡流量统

#!/bin/bash
NAME=nic_flow
PIDFILE=/var/tmp/$NAME.pid
LOGFILE=/var/tmp/$NAME.log

function start(){
    if [ -f "$PIDFILE" ]; then
        echo $PIDFILE
        exit 2
    fi
    for (( ; ; ));do
        eth=$1
        [ -z "${eth:-}" ] && eth=eth0
        time_range=$2
        [ -z "${time_range:-}" ] && time_range=1      
        ifconfig  | awk '{print $1}' | grep "eth" > /dev/null 
        [ $? -gt 0 ] && echo "wrong NIC device" && exit 10
        RX_1=$(cat /proc/net/dev | grep "$eth" | awk -F'[ |:]+'  '{print $4}')
        TX_1=$(cat /proc/net/dev | grep "$eth" | awk '{print $9}')
        sleep $time_range
        RX_2=$(cat /proc/net/dev | grep "$eth" | awk -F'[ |:]+'  '{print $4}')
        TX_2=$(cat /proc/net/dev | grep "$eth" | awk '{print $9}')
        clear
        echo  -e "`date +%k:%M:%S`      RX        TX" | tee -a $LOGFILE 
        RX=$((${RX_2}-${RX_1}))
        TX=$((${TX_2}-${TX_1}))
        if [[ $RX -lt 1024 ]];then
            RX="${RX}B/s"
        elif [[ $RX -gt 1048576 ]];then
            RX=$(echo $RX | awk '{print $1/1048576 "MB/s"}')
        else
            RX=$(echo $RX | awk '{print $1/1024 "KB/s"}')
        fi
        if [[ $TX -lt 1024 ]];then
            TX="${TX}B/s"

        elif [[ $TX -gt 1048576 ]];then
            TX=$(echo $TX | awk '{print $1/1048576 "MB/s"}')
        else
            TX=$(echo $TX | awk '{print $1/1024 "KB/s"}')
        fi 
        echo -e " $eth       $RX        $TX " | tee -a $LOGFILE
    done& 
    echo $! > $PIDFILE
} 
function stop(){
    [ -f $PIDFILE ] && kill `cat $PIDFILE` && rm -rf $PIDFILE
}

case "$1" in
  start)
    start $2 $3
    ;;
  stop)
    stop
    ;;
  *)
    echo $"Usage:$0  {start|stop,NIC device(eth*), time_range(s)}"
    exit 2
esac

 今天发现一个更好用的工具nicstat。

nicstat可以提供更加全面的网卡信息。
          显示TCP流量统计
          显示UDP流量统计
          报告进出网卡的字节数
          报告进出网卡的数据数
          报告网卡利用率
          报告NIC饱和度和其他信息

 

 

 

完整的安装过程（基于centos 6.3 x86_64，如果是ubuntu或者其linux可以参照官网文档）? 

 安装make环境
yum install gcc gcc-c++ make automake autoconf -y

由于nicstat依赖32 bit glibc package，所以
yum install libgcc.i686 glibc.i686 glibc-devel.i686  -y

下载文件并安装

cd /usr/local/src
wget http://nchc.dl.sourceforge.net/project/nicstat/nicstat-1.92.tar.gz
tar xf nicstat-1.92.tar.gz
cd nicstat-1.92
cp Makefile.Linux Makefile
make
