zabbix数据库优化脚本

分享一个zabbix数据库的优化脚本，适合2.0版本。

对history，hostory_uint按日分区，trends,trends_uint按月分区；

关闭Houserkeeper:

vim zabbix_server.conf

DisableHousekeeper=1

对history,hostory_uint每日建立第二天的分区并删除45天前的分区

对trends,trends_uint每月20号建立下一个月的分区，并删除12个月前的分区

时间可以自己修改

由于events表的大小对仪表盘的展示速度影响很大，2.0以后的版本又对该表做过修改，具有主键约束，不能以clock做分区表优化，所以我每日都清理该表，只保留了3天的数据（根据自己的环境和需求而定，可以自己修改），很简单的一个定期维护脚本，希望能帮到大家
