zabbix------了解zabbix

tips：大家可以参考官方文档，这是解决问题的啊https://www.zabbix.com/documentation/2.4/manual
1 了解zabbix
Zabbix is software that monitors numerous parameters of a network and the health and integrity of servers. Zabbix uses a flexible notification mechanism that allows users to configure e-mail based alerts for virtually any event. This allows a fast reaction to server problems. Zabbix offers excellent reporting and data visualisation features based on the stored data. This makes Zabbix ideal for capacity planning.
大致意思：Zabbix是监控网络主机hosts的健康状态并根据事件events发送通知notification给zabbix用户以快速解决问题。由于zabbix性能良好的数据存储显示特性，zabbix适合大容量的高级别的监控。
2 zabbix术语

host，hostgroup:
a networked device that you want to monitor, with IP/DNS
zabbix把监控的单位称为host，host可能是一个Router，一个Linux Server，一个打印机，而一类host，为了区分host，引入hostgroup
item:
a particular piece of data that you want to receive off of a host, a metric of data.
item有点像zabbix模板的基本单位，有了item就好像手机app的一个项目，这个项目负责让服务器可以取host数据
trigger:

a logical expression that defines a problem threshold and is used to “evaluate” data received in itemsWhen received data are above the threshold, triggers go from 'Ok' into a 'Problem' state. When received data are below the threshold, triggers stay in/return to an 'Ok' state

trigger称为触发器，是一个表达式。当发生某个事件（比如内存剩余少于100M）就触发，实现某种形式的状态转移，比如problem-->ok

event
a single occurrence of something that deserves attention such as a trigger changing state or a discovery/agent auto-registration taking place

那些触发trigger的发生的事情称为一个事件

action

a predefined means of reacting to an event.
An action consists of operations (e.g. sending a notification) and conditions (when the operation is carried out)
当事件发生了（比如服务器挂掉了，比如有新机器加入），action针对condition（你定义的比如对哪些主机，满足哪些具体条件）采取相应的动作operation
escalation
a custom scenario（方案） for executing operations within an action; a sequence of sending notifications/executing remote commands

告警机制，触发动作而通知或执行脚本的解决方案

media
a means of delivering notifications; delivery channel

通知媒介，比如短信SMS，比如Email等

template
a set of entities (items, triggers, graphs, screens, applications, low-level discovery rules, web scenarios) ready to be applied to one or several hosts
The job of templates is to speed up the deployment of monitoring tasks on a host; also to make it easier to apply mass changes to monitoring tasks. Templates are linked directly to individual hosts.
模板嘛，就是包含了条目，触发器，图表，屏幕，应用，自动发现规则，网络分析的框架

Zabbix proxy
a process that may collect data on behalf of Zabbix server, taking some processing load off of the server
Zabbix服务器的代理，收集host数据以帮助缓解服务器的负载
