1.什么是HaTop
HATop 是一个交互式的基于 ncurses 开发的实时监控 HAProxy 负载均衡系统的统计工具。后来有人对该工具进行改进,增加了 TCP 支持
2.安装部署
在安装之前需要开启haproxy的sock
修改

stats socket /tmp/haproxy.sock

cd /usr/local/src/
wget https://github.com/Wirehive/hatop/archive/master.zip

unzip master.zip
cd hatop–master/
install –m 755 bin/hatop /usr/local/bin
install –m 644 man/hatop.1 /usr/local/share/man/man1
gzip /usr/local/share/man/man1/hatop.1

以上可以直接复制黏贴就可以实现了,具体的参数在hatop-master/README 可以了解到
3.HaTop使用

|
hatop –s /tmp/haproxy.sock

按q键退出,运行界面分为5大块 (界面切换分别按 1 2 3 4 5 来选择)
很多参数在上面的hatop-master/README 文件中可以了解的,界面也很清晰的告诉我们多少个机器是OK的
