說明腳本配置成功
[root@oracle zabbix]# vim etc/zabbix_agentd.conf
把下面這兩行配置加到最后：
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，之前安裝過orabbix,直接在Template_Oracle下的自動發現規則下新建自動發現規則：
在自動發現規則下添加監控原型：
然后在圖形原型配置、並將上面的三個原型添加進去：
最后設置觸發器：
（這里是以autopercent為判斷條件，>95時產生告警）
最后重啟客戶端的zabbix_agent
修改服務端的zabbix_server.conf的CacheSize至256M
重啟服務端的zabbix_server和orabbix
