一、nicstat 安装
1、下载源码
wget wget -c http://nchc.dl.sourceforge.net/project/nicstat/nicstat-1.92.tar.gz
2、编译安装
tar xf nicstat-1.92.tar.gz
cd nicstat-1.92
cp Makefile.Linux Makefile
vim Makefile
17 #CFLAGS = $(COPT)
make
二、nicstat 使用
1、查看帮助
# ./nicstat.sh -h
USAGE: nicstat [-hvnsxpztual] [-i int[,int...]]
[-S int:mbps[,int:mbps...]] [interval [count]]
-h # help
-v # show version (1.92)
-i interface # track interface only
-n # show non-local interfaces only (exclude lo0)
-s # summary output
-x # extended output
-p # parseable output
-z # skip zero value lines
-t # show TCP statistics
-u # show UDP statistics
-a # equivalent to "-x -u -t"
-l # list interface(s)
-M # output in Mbits/sec
-S int:mbps[fd|hd] # tell nicstat the interface
# speed (Mbits/sec) and duplex
eg,
nicstat # print summary since boot only
nicstat 1 # print every 1 second
nicstat 1 5 # print 5 times only
nicstat -z 1 # print every 1 second, skip zero lines
nicstat -i hme0 1 # print hme0 only every 1 second
2、字段解释
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
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
3、使用实例
1) 一次性查看网络流量
# ./nicstat.sh
