# 安装环境 #

Centos 6.4

nicstat 1.9.2

# 安装步骤 #

获取源码包

wget http://surfnet.dl.sourceforge.net/project/nicstat/nicstat-src-1.92.tar.gz

nicstat安装

tar -zxvf nicstat-src-1.92.tar.gz
    cp Makefile.Linux Makefile
    make
    make install

注意，需要修改Makefile文件，因为nicstat默认是是32位操作系统下编译的，修改MakeFile如下：

#CFLAGS =       $(COPT) -m32
    CFLAGS =        $(COPT)

nicstat使用

[root@centos6-mysql-172 nicstat-src-1.92]# enicstat 1

默认是以KB为计算单位，也可以Mb为计算单位

其中%Util以及sat（This the number of errors/second seen for the interface）参数非常有用

nicstat亦可统计tcp以及udp
