使用vnstat监控流量

vnstat通/proc来监控流量，无需root权限，提供每日、每月等报表，并有php前台扩展。

经过几个月运行发现有时vnstat -d 只能看最近几天的
http://humdi.net/vnstat/

wget http://humdi.net/vnstat/vnstat-1.6.tar.gz
tar zxvf vnstat-1.6.tar.gz
cd vnstat-1.6
make && make install ; vnstat –testkernel && vnstat -u -i eth0

如果用户在一个64位平台上编译，应改用make 64bit命令.

添加crontab
crontab -e
0-55/5 * * * * if [ -x /usr/bin/vnstat ] && [ `ls/var/lib/vnstat/ | wc -l` -ge 1 ]; then /usr/bin/vnstat -u; fi
