zabbix3.2-proxy实现分布式监控

A Zabbix proxy can collect performance and availability data on behalf of the Zabbix server. This way, a proxy can take on itself some of the load of collecting data and offload the Zabbix server.
Also, using a proxy is the easiest way of implementing centralized and distributed monitoring, when all agents and proxies report to one Zabbix server and all data is collected centrally.
A Zabbix proxy can be used to:
Monitor remote locations
Monitor locations having unreliable communications
Offload the Zabbix server when monitoring thousands of devices
Simplify the maintenance of distributed monitoring
