与天地兮比寿，与日月兮齐光。这篇文章主要讲述Zabbix对Linux主机监控相关的知识，希望能为你提供帮助。
zabbix是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。zabbix能监视各种网络参数，保证服务器系统的安全运营；并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。zabbix由2部分构成，zabbix server与可选组件zabbix agent。zabbix server可以通过SNMP，zabbix agent，ping，端口监视等方法提供对远程服务器/网络状态的监视，数据收集等功能，它可以运行在Linux，Solaris，HP-UX，AIX，Free BSD，Open BSD，OS X等平台上。
zabbix对对象的监控可以是主动式也可以被动式，在下面先演示被动式监控linux主机的基本配置，需要对被监控对象安装agent，才能收集到监控对象中定义好的数据，并用图表方式展示在网页上。


1.被监控的Linux主机上安装zabbix-agent及配置下面所有的配置是在上篇博文基础上继续演进进行配置。
