Version: zabbix 3.0
一、配置网络发现规则（Configuration Discovery）
Device uniqueness criteria：选择主机名作为唯一标识(Configuation Hosts中显示的NAME)
二、查看发现的主机（Monitoring->Discovery）
ps: 显示主机名(m-proxy1)需要在服务器端/etc/hosts定义
192.168.0.2 m-proxy1
三、自动添加Hosts（加入到对应组,links对应模板）（Configuration -> Actions Event -> Discovery）
现在可以看到添加的主机(Configuation->Hosts)
Q&S
步骤一后 并未发现hosts
Solve:
1 tcpdump -vnn host 172.16.0.116 and port 10050 #发现服务器并没有发送discovery包到客户端
2 日志开启 debugging (DebugLevel=5)

需要TLS支持(yum install -y openssl openssl-devel) configure --with-openssl
(2.0网络发现没有这个要求)
