一、概述

使用HA后在配置文件里边配置了监控页面信息后，可以在浏览器中访问地址去看到。

#haproxy监控页面地址
listen  admin_stat
        #haproxy的web管理端口 8888，自行设置
        bind 0.0.0.0:8888
        mode    http
        stats   refresh 30s
        #haproxy web管理url，自行设置
        stats uri /haproxy_stats
        stats realm Haproxy\ Statistics
        #haproxy web管理用户名密码，自行设置
        stats auth admin:admin
        stats hide-version

除了上边这种方法还可以通过echo "show stat" | socat /var/lib/haproxy/stats stdio这条命令来看到上边的输出信息

这些指标具体是什么含义，了解这些指标之后，我相信对HA的理解会更进一步。
