简介
zabbix是一个基于WEB界面的提供分布式网络监视功能的企业级的开源解决方案。相对于cacti和nagios而言,zabbix最大的特点是分布式监控,自动发现,自定义监控项目。
一、监控系统所具备的四个要素
1、数据采集
zabbix采集数据的手段有SNMP、zabbix的Agent、IPMI agent、web monitoring、database monitoring,Internal check、calculated monitoring、custom command monitoring、ping或端口检查等。
2、数据存储
zabbix将数据存储在RDBMS中。
3、数据展示
zabbix使用php开发的程序进行绘图。
4、事件报警
zabbix通知机制有:E-mail、SMS、Jabber、Chat message、Command execution。
二、Zabbix组件概述
zabbix-serve:负责接收agent发送的报告信息,所有配置、统计数据及操作数据都有此组件组织进行;
database:用于存储配置信息和zabbix收集的数据
web-interface:zabbix的GUI接口,通常与server运行在同一台主机上;
proxy:可选组件,常用于分布式监控环境中,代替server收集其他被监控端的监控数据,并统一发送到server端。
Agent:部署在被监控主机上,负责收集本地数据发往server或proxy端。
三、zabbix的术语
主机(host):要监控的网络设备统称;
主机组(host group):主机的逻辑容器,可以包含主机和模板;
监控项(item):一个特定监控指标和对应的数据,每个item由key进行标示;
trigger(触发器):一个表达式,用于评估某监控对象的某个特定的item所接收的数据是否在合理范围内,即阈值,状态分为“OK”和“problem”。
事件(event):发生的一个值得关注的事情,如:触发器的状态转变,新的agent上线或自动发现等操作。
动作:对于指定的event发生以后所采定义的处理方法,如发送通知或报警;
报警升级(escalation):发送警告信息的方案,如果在定义内的警告次数之内没有处理,将向上级发送报警短信;
媒介(media):发送通知的手段,如Email、SMS、Jabber等。
通知(notification):通过媒介向用户发送某事件的信息。
四、一键安装脚本
说明:此脚本只适用与RHEL6.x系列;Nginx版本为1.6最新稳定版;PHP为5.4最新版;Mysql为5.5最新稳定版;Zabbix暂时为2.4最新版。
只要你能连上网络,只要你会运行脚本。那你就会完成zabbix的部署安装了,内嵌yum源及LNMP及zabbix的下载安装!!真正的实现一步到位!!

五、配置WEB页面
地址:IP地址
至此zabbix一键部署安装就完成了,请多提意见!谢谢

最后chkconfig mysql on少个d 最小化安装需要安装下wget 其他ok 速度很快。
@xuyilin:这个平台非管理员,文章一旦提交就暂时无法修改了,谢谢你的提示!
