Network Discovery rules and auto-add hosts

Version:zabbix 3.0

I. Configuring Network Discovery Rules

Device Uniqueness Criteria: Select the hostname as the unique identifier (the name shown in the configuation hosts)

Second, view the discovered host (Monitoring->discovery)

PS: Display (API-1) needs to be defined in/etc/hosts 172.16.0.116 api-1

Third, automatically add the hosts (join the corresponding group, links corresponding template)

You can now see the added host (configuation->hosts)

Q&s

The hosts were not found after step one

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
