zabbix 之 orabbix安装指导

zabbix利用orabbix监控oracle

Orabbix 是一个用来监控 Oracle 数据库实例的 Zabbix 插件。下载地址： http://www.smartmarmot.com/product/orabbix/download/
Orabbix插件的安装与配置
确保安装jdk环境，java version查看,没有则通过yum来安装JAVA：yum install java

1.在/opt目录下新建一个orabbix目录：

[root@oracle orabbix]#mkdir -p /opt/orabbix

（建议在此目录下，如果放置其他目录稍后需要更改orabbix的启动文件orabbix,启动文件默认写在opt/orabbix目录下 ）

2. 解压安装文件

cd /opt/orabbix
unzip orabbix-1.2.3.zip

3.赋予权限

chmod -R a+x /opt/orabbix/

4 通过/opt/orabbix/conf/config.props.sample文件创建一个config.props文件：

cp /opt/orabbix/conf/config.props.sample /opt/orabbix/conf/config.props

5. 编辑orabbix配置文件,具体如下
[root@oracle orabbix]#vi conf/config.props

ZabbixServerList=ZabbixServer1

ZabbixServer1.Address=10.0.0.10
ZabbixServer1.Port=10051

#ZabbixServer2.Address=IP_ADDRESS_OF_ZABBIX_SERVER
#ZabbixServer2.Port=PORT_OF_ZABBIX_SERVER

#pidFile
OrabbixDaemon.PidFile=./logs/orabbix.pid
#frequency of item's refresh
OrabbixDaemon.Sleep=300
#MaxThreadNumber should be >= than the number of your databases
OrabbixDaemon.MaxThreadNumber=100

#put here your databases in a comma separated list
DatabaseList=rac1,rac2

#Configuration of Connection pool
#if not specified Orabbis is going to use default values (hardcoded)
#Maximum number of active connection inside pool
DatabaseList.MaxActive=10
#The maximum number of milliseconds that the pool will wait
#(when there are no available connections) for a connection to be returned
#before throwing an exception, or <= 0 to wait indefinitely.
DatabaseList.MaxWait=100
DatabaseList.MaxIdle=1

#define here your connection string for each database
rac1.Url=jdbc:oracle:thin:@10.0.0.3:1521:racdb1
rac1.User=zabbix
rac1.Password=zabbix
#Those values are optionals if not specified Orabbix is going to use the general values
rac1.MaxActive=10
rac1.MaxWait=100
rac1.MaxIdle=1
rac1.QueryListFile=./conf/query.props

rac2.Url=jdbc:oracle:thin:@10.0.0.4:1521:racdb2
rac2.User=zabbix
rac2.Password=zabbix
#Those values are optionals if not specified Orabbix is going to use the general values
rac2.MaxActive=10
rac2.MaxWait=100
rac2.MaxIdle=1
rac2.QueryListFile=./conf/query.props
#rac2.Url=jdbc:oracle:thin:@server2.domain.example.com:<LISTENER_PORT>:rac2
#rac2.User=zabbix
#rac2.Password=zabbix_password
#rac2.QueryListFile=./conf/query.props

#DB3.Url=jdbc:oracle:thin:@server3.domain.example.com:<LISTENER_PORT>:DB3
#DB3.User=zabbix
#DB3.Password=zabbix_password
#DB3.QueryListFile=./conf/query.props

在数据库服务器上（注意，是数据库服务器）创建zabbix用户如下步骤：

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

GRANT CONNECT TO ZABBIX;

GRANT RESOURCE TO ZABBIX;

ALTER USER ZABBIX DEFAULT ROLE ALL;

GRANT SELECT ANY TABLE TO ZABBIX;

GRANT CREATE SESSION TO ZABBIX;

GRANT SELECT ANY DICTIONARY TO ZABBIX;

GRANT UNLIMITED TABLESPACE TO ZABBIX;

GRANT SELECT ANY DICTIONARY TO ZABBIX;

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

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

commit;

6. 创建执行文件（直接cp即可）

cp /opt/orabbix/init.d/orabbix /etc/init.d/orabbix

7.保存退出，启动orabbix服务(确保有执行权限)

/etc/init.d/orabbix start

Orabbix服务加入随系统启动：

chkconfig --add orabbix
chkconfig --level 345 orabbix on

常见问题：
若config.props文件未配置，或是配置了错误，无法通过配置的信息正确连进Oracle数据库的，会出现以下错误信息
[root@zabbix orabbix]# /etc/init.d/orabbix start

Starting Orabbix service:
[root@zabbix orabbix]# Stopping
java.lang.Exception: ERROR on main - Connections is empty
atcom.smartmarmot.orabbix.Orabbixmon.run(Orabbixmon.java:101)
atcom.smartmarmot.orabbix.bootstrap.main(bootstrap.java:50)

可查看log信息判断解决
[root@oracle orabbix]# tail -f /opt/orabbix/logs/orabbix.log

到此，安装配置完成，则通过web页面访问直接导入模块即可，模板文件：
Orabbix_export_full.xml
导入后生成template模板名为：Template_Oracle
将oracle主机host与导入的模板Template_Oracle关联；
注意：zabbix页面中配置oracle主机host名称必须和上面DatabaseList=rac1,rac2中的rac1、rac2一致，并且大小写敏感！！！！
