说明脚本配置成功
[root@oracle zabbix]# vim etc/zabbix_agentd.conf
把下面这两行配置加到最后：
UserParameter=ora.tab.discovery,/usr/local/zabbix/scripts/oracle_discovery.sh
UserParameter=tablespace[*],/usr/local/zabbix/scripts/oracle_check.sh $1 $2
在zabbix_server端添加discovery模板，之前安装过orabbix,直接在Template_Oracle下的自动发现规则下新建自动发现规则：
在自动发现规则下添加监控原型：
然后在图形原型配置、并将上面的三个原型添加进去：
最后设置触发器：
（这里是以autopercent为判断条件，>95时产生告警）
最后重启客户端的zabbix_agent
修改服务端的zabbix_server.conf的CacheSize至256M
重启服务端的zabbix_server和orabbix
