nicstat:网络流量监控利器
nicstat prints out network statistics for all network cards (NICs), including packets, kilobytes per second, average packet sizes and more.

官网摘要:nicstat is to network interfaces as "iostat" is to disks, or "prstat" is to processes. It is designed as a much better version of "netstat -i". Its differences include:* Reports bytes in & out as well as packets.* Normalizes these values to per-second rates.* Reports on all interfaces (while iterating)* Reports Utilization (rough calculation as of now)* Reports Saturation (also rough)* Prefixes statistics with the current time
如何安装:（OS：ubuntu12.04 server x86_64）
1:安装编译环境：$ sudo apt-get install build-essential
2:下载源码包：$ wget http://sourceforge.net/projects/nicstat/files/nicstat-1.92.tar.gz
3:解压：$ tar -zxvf nicstat-1.92.tar.gz
4:安装：$ cd nicstat-1.92/$ cat README.txt #可根据此文本安装$ cp Makefile.Linux Makefile$ uname -a Linux ubuntu-s2 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 GNU/Linux$ sudo vim Makefile CFLAGS = $(COPT) -m32 #将此行修改为如下： CFLAGS = $(COPT)$ sudo make$ sudo mkdir /usr/local/share/man/man1 #如若无此步会报如下错： install:cannot create regular file `/usr/local/share/man/man1/nicstat.1': No such file or directory$ sudo make install
如何使用：
概要：（enicstat和nicstat使用方法一致）nicstat [-hvnsxpztualkM] [-iinterface] [-Sint:mbps[fd|hd]] [interval [count]]
选项：-h #显示简单的用法-v #显示nicstat版本-n #只统计非本地（即非回环）接口-s #显示摘要输出（只是接收和发送的数据量）-x #显示扩展的输出-M #以Mbps显示吞吐量,而不是默认的KB/s-p #以解析后的输出格式显示-z #跳过采样周期内是零流量的接口-t #tcp流量统计-u #ucp流量统计-a #等同于'-x -t -u'-l #只显示端口状态-i interface[,interface...] #指定接口
字段描述：
Time #抽样结束的时间 Int #网卡名 rKB/s,InKB #每秒读的千字节数(received) wKB/s,OutKB #每秒写的千字节数(transmitted) rMbps,RdMbps #每秒读的百万字节数K(received) wMbps,WrMbps #每秒写的百万字节数M(transmitted) rPk/s,InSeg,InDG #每秒读的数据包 wPk/s,OutSeg,OutDG #每秒写的数据包 rAvs #平均读的数据包大小 wAvs #平均写的数据包大小 %Util #接口的利用率百分比 Sat #每秒的错误数，接口接近饱和的一个指标更多请参考手册
示例：$ nicstat 3 #每3秒显示一次$ nicstat 3 5 #每3秒显示一次共显示5次$ nicstat -i eth0 #只显示eth0的状态$ nicstat -M #以Mbps为单位显示吞吐量
