Zabbix优化之必杀技-表分区
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
