4. Zabbix概述

架构

Zabbix主流软件包中包含如下组件

Server

Zabbix Server为中心组件，用来获取agent存活状况及监控数据和统计. 所有的配置、统计、操作数据均通过Server进行存取.

数据库

所有的Zabbix数据均存储在数据库中

Web接口

为了更简单的无障碍的访问Zabbix, 所以提供了web接口. 该接口作为Zabbix Server的一部分，通常(也有技术控不这样做)和server运行在同一台主机上.

Warning

如果采用SQLite作为数据库，web接口和Zabbix Server必须运行在同一台主机上

Proxy

Zabbix Proxy能够代替Zabbix Server进行性能及可用性数据采集. Proxy是Zabbix部署的可选组件。 如果想分担单一Zabbix Server负载，推荐使用proxy.

Agent

Zabbix agents 部署在目标监控机上并监控本地资源和应用，将收集数据汇报给Zabbix Server

数据流

In addition it is important to take a step back and have a look at the overall data flow within Zabbix. In order to create an item that gathers data you must first create a host. Moving to the other end of the Zabbix spectrum you must first have an item to create a trigger. You must have a trigger to create an action. Thus if you want to receive an alert that your CPU load it too high on Server X you must first create a host entry for Server X followed by an item for monitoring its CPU, then a trigger which activates if the CPU is too high, followed by an action which sends you an email. While that may seem like a lot of steps, with the use of templating it really isn’t. However, due to this design it is possible to create a very flexible setup.
