 前言,使用zabbix最大的瓶颈在于数据库,维护好zabbix的数据存储,告警,即能够很好的应用zabbix去构建监控系统。本文所讲的正是数据存储部分。本文所针对的用户,需要对zabbix有一定概念,对MySQL熟悉,掌握存储过程的书写,对zabbix数据库字段熟悉

  本部分内容来自本人的新书,作为对新书分表章节的部分补充,书名叫《zabbix监控系统》,将于2014-06与读者面市。书的章节目录已经放在github上面

https://github.com/itnihao/zabbix-book/blob/master/README.md

Zabbix中历史数据的

zabbix对数据将数据存于数据库,其主要将历史数据存于history和trends的2个表中,如下

1)历史数据的表

2)警告日志数据的表

  尽管将housekeeper功能已经关闭,但zabbix-server和WEB前端仍然会记录数据到housekeeper表,这里为了防止写入数据,将其表的引擎设置为BLACKHOLE,使其不可写。
