一 、Orabbix 介绍

orabbix是一个用来监控oracle数据库性能的zabbix插件工具，通过安装在被监控服务器上客户端上收集数据并传给zabbix服务器端，然后通过调用图形显示。具有以下功能：

1. 数据库版本

2. 归档文件

3. 等待的事件(如文件的I/O，单块的读，多块的读，直接读，SQLNet消息，控制文件I/O，日志写等)

4. HitRatio(监控Hit Ratio的触发，表/存储过程，SQLArea，Body)

5. 逻辑I/O(当前读操作，持续的读操作，块的更改)

6. PGA

7. SGA(固定的缓冲，JAVApool，Large Pool，Log Buffer，Shared Pool，Buffer Cache)

8. 物理I/O(重写操作，数据文件写操作，数据文件读操作)

9. SharePool(PoolDictionary Cache, Pool Free Memory, Library Cache,Sql Area ,Misc.)

10. Pin Hit Ratio(monitor Hit Ratio on Trigger, Tables/Procedures, SQLArea,Body)

11. Session/Processes(monitor Sessions and processes)

12. Session (ActiveSession, Inactive Sessions, System Session)

二、创建Oracle监控账号并赋权

CREATE  USER zabbix IDENTIFIED BY ys_zb_0418 DEFAULT TABLESPACE USERS TEMPORARY TABLESPACE TEMP PROFILE DEFAULT ACCOUNT UNLOCK;

GRANT  ALTER SESSION TO zabbix;

GRANT CREATE SESSION TO zabbix;

GRANT CONNECT TO zabbix;

ALTER USER zabbix DEFAULT ROLE ALL;

GRANT SELECT ON V_$INSTANCE TO zabbix;

GRANT SELECT ON DBA_USERS TO zabbix;

GRANT SELECT ON V_$LOG_HISTORY TO zabbix;

GRANT SELECT ON V_$LOG TO zabbix;

GRANT SELECT ON V_$PARAMETER TO zabbix;

GRANT SELECT ON SYS.DBA_AUDIT_SESSION TO zabbix;

GRANT SELECT ON V_$LOCK TO zabbix;

GRANT SELECT ON DBA_REGISTRY TO zabbix;

GRANT SELECT ON V_$LIBRARYCACHE TO zabbix;

GRANT SELECT ON V_$SYSSTAT TO zabbix;

GRANT SELECT ON V_$PARAMETER TO zabbix;

GRANT SELECT ON V_$LATCH TO zabbix;

GRANT SELECT ON V_$PGASTAT TO zabbix;

GRANT SELECT ON V_$SGASTAT TO zabbix;

GRANT SELECT ON V_$LIBRARYCACHE TO zabbix;

GRANT SELECT ON V_$PROCESS TO zabbix;

GRANT SELECT ON DBA_DATA_FILES TO zabbix;

GRANT SELECT ON DBA_TEMP_FILES TO zabbix;

GRANT SELECT ON DBA_FREE_SPACE TO zabbix;

GRANT SELECT ON V_$SYSTEM_EVENT TO zabbix;

GRANT SELECT ON V_$locked_object TO zabbix;

GRANT SELECT ON dba_objects TO zabbix;

GRANT SELECT ON dba_tablespaces TO zabbix;

GRANT SELECT ON v_$SESSION TO zabbix;注意: 如果是oracle11g的数据库版本，还需要执行下面的语句开放ACL的访问控制，否则在监控的过程中有部份内容无法正常显示(例于数据库版本，数据库文件大小等)，而且orabbix的日志显示中也会有错误提示

execdbms_network_acl_admin.create_acl(acl =>'resolve.xml',description=>'resolve acl', principal =>'ZABBIX', is_grant =>true,privilege=>'resolve');

execdbms_network_acl_admin.assign_acl(acl =>'resolve.xml', host =>'*');

commit;

# --执行过程

三、安装配置orabbix安装JDK

tar -xf jdk-7u79-linux-x64.tar.gz -C /usr/local/

安装orabbix# mdkir -p /usr/local/orabbix

# mv orabbix-1.2.3.zip /usr/local/orabbix

# unzip orabbix-1.2.3.zip

# chmod +x run.sh

# cp init.d/orabbix /etc/init.d/

# sed -i 's#/opt/orabbix#orabbix=/usr/local/orabbix#g' /etc/init.d/orabbix

# chmod +x /etc/init.d/orabbix

# sed -i 's#java#//usr/local/jdk1.7.0_79/bin/java#g' /usr/local/orabbix/run.sh

准备orabbix 配置文件# cp config.props.sample  config.props

# vim config.props

需要注意的是DatabaseList=App01指的是被监控服务器的名称，该名称要和zabbix server界面中的机器名称保持一致，该配置文件中后续所引用的设定都以该名称为准。

App01.Url=jdbc:oracle:thin:@ 192.168.154.130:1521:orcl指定的是被监控服务器的连接信息(例如采用jdbc的联接方式，服务器地址是 192.168.154.130，oracle的端口是1521，orcl指的是数据库的实例名称)

3. 配置 orabbix 启动脚本 并启动orabbix

# service orabbix start

4. 导入oracle 监控模板
