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由zabbix server与可选组件zabbix agent两部门组成。

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。
 zabbix agent需要安装在被监视的目标服务器上，它主要完成对硬件信息或与操作系统有关的内存，CPU等信息的收集。
zabbix的主要特点：

- 安装与配置简单，学习成本低 

- 支持多语言（包括中文）

- 免费开源

- 自动发现服务器与网络设备

- 分布式监视以及WEB集中管理功能

- 可以无agent监视

- 用户安全认证和柔软的授权方式

- 通过WEB界面设置或查看监视结果

- email等通知功能

等等
Zabbix主要功能：

- CPU负荷

- 内存使用

- 磁盘使用

- 网络状况

- 端口监视

请看我用dockerfile构建zabbix agent
