iftop
依赖：
yum -y install flex byacc libpcap ncurses ncurses-devel libpcap-devel
yum -y install gcc
编译安装
wget http://www.ex-parrot.com/pdw/iftop/download/iftop-0.17.tar.gz
tar zxvf iftop-0.17.tar.gz
cd iftop-0.17
./configure
make && make install
查看
iftop -n -P -b -i eth0
nload
yum -y install epel-release
如果epel-release无法安装
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm
然后安装
yum -y install nload
nload device eth0
也可以编译安装
yum -y install gcc gcc-c++ ncurses-devel
wget http://www.roland-riegel.de/nload/nload-0.7.4.tar.gz
tar zxvf nload-0.7.4.tar.gz
cd nload-0.7.4
./configure
make && make install
vnstat
yum -y install epel-release
yum -y install vnstat
查看网卡
ip addr
创建监控数据库
vnstat -u -i eth0添加权限
chmod 666 /var/lib/vnstat/eth0
chmod 666 /var/lib/vnstat/.eth0
开机启动
systemctl enable vnstat
systemctl start vnstat
systemctl stop vnstat
systemctl disable vnstat
流量查看
vnstat -l # 实时流量
vnstat -h # 小时
vnstat -d # 日流量
vnstat -w # 周流量
vnstat -m # 月流量
vnstat -t # 流量最高top10天
图片输出
/usr/bin/vnstati -d -o /root/day.png需要带时间，新建sh
#!/bin/bash
date=$(date +%Y%m%d%H);/usr/bin/vnstati -d -o /usr/share/nginx/html/${date}.jpg
如果提示：Error: Interface "eth0" not available, exiting
修改/etc/vnstat.conf文件
Interface "eth0"
改为实际网卡名称，重启systemctl start vnstat即可
