网络发现规则及自动添加hosts

Posted 2020-06-22 metasequoia

Version: zabbix 3.0

一、配置网络发现规则

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(api-1)需要在/etc/hosts定义 172.16.0.116　　api-1

 

三、自动添加Hosts(加入到对应组,links对应模板)

 

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)

tail -f /tmp/zabbix_server.log | grep discover

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)
