zabbix通过Orabbix监控oracle数据库
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.它是通过JDBC监控数据库的
能对以下进行监控：
[*]DB Version (i.e. Validity of package)
[*]Archiving (Archive log production with trend analysis)
[*]Event Waits (Files I/O, single block read, multi-block read, direct path read, SQLNet Messages, Control file I/O, Log Write)
[*]Hit Ratio (Hit Ratio on Triggers, Tables/Procedures, SQL Area, Body)
[*]Logical I/O (Server performance on Logical I/O of: Current Read, Consistent Read, Block Change)
[*]Physical I/O (Redo Writes, Datafile Writes, Datafile Reads)
[*]PGA
[*]SGA (In particular; Fixed Buffer, Java Pool, Large Pool, Log Buffer, Shared Poolm Buffer Cache)
[*]Shared Pool (Pool Dictionary Cache, Pool Free Memory, Library Chache, SQL Area, MISC.)
[*]Pin Hit Ratio (Oracle library cache pin are caused by contention with the library cache, the area used to store SQL executables for re-use)
[*]Sessions / Processes
[*]Sessions (Active Sessions, Inactive Sessions, System Sessions)
DBSize/DBFileSize (DBSize>
1. 需要的条件
[*]Zabbix Server -->这里我使用的是zabbix-3.2.6
[*]Java Runtime Environment -->我用的是dk1.7.0_80
2. 安装orabbix
2.1 下载orabbix
http://sourceforge.net/projects/orabbix/files/orabbix-1.2.3.zip/download
mkdir /opt/orabbix
mv orabbix-1.2.3.jar /opt/orabbix
cd /opt/orabbix
unzip orabbix-1.2.3.zip
2.2添加服务启动脚本，和相关脚本赋权
cp /opt/orabbix/init.d/orabbix /etc/init.d/
chmod u+x /etc/init.d/orabbix
chmod u+x /opt/orabbix/run.sh
chkconfig --add orabbix
chkconfig orabbix on
run.sh还需要进行修改，将java改成你的JDK中java命令的绝对路径
/usr/java/jdk1.7.0_80/bin/java -Duser.language=en -Duser.country=US -Dlog4j.configuration=./conf/log4j.properties -cp $(for i in lib/*.jar ; do echo -n $i: ; done).:./orabbix-1.2.3.jar com.smartmarmot.orabbix.bootstrap start ./conf/config.props &
2.3 在oracle数据库上创建zabbix用户，并授权
CREATE USER zabbix
IDENTIFIED BY zabbix
DEFAULT TABLESPACE SYSTEM
TEMPORARY TABLESPACE TEMP
PROFILE DEFAULT
ACCOUNT UNLOCK;
– 2 Roles for ZABBIX
GRANT CONNECT TO ZABBIX;
GRANT RESOURCE TO ZABBIX;
ALTER USER ZABBIX DEFAULT ROLE ALL;
– 5 System Privileges for ZABBIX
GRANT SELECT ANY TABLE TO ZABBIX;
GRANT CREATE SESSION TO ZABBIX;
GRANT SELECT ANY DICTIONARY TO ZABBIX;
GRANT UNLIMITED TABLESPACE TO ZABBIX;
GRANT SELECT ANY DICTIONARY TO ZABBIX;
如果需要严格的权限控制，可以执行如下脚本
CREATE USER zabbix
IDENTIFIED BY zabbix
DEFAULT TABLESPACE USERS
TEMPORARY TABLESPACE TEMP
PROFILE DEFAULT
ACCOUNT UNLOCK;
GRANT>
GRANT CREATE SESSION TO ZABBIX;
GRANT CONNECT TO ZABBIX;
ALTER USER ZABBIX DEFAULT ROLE ALL;
GRANT SELECT ON V_$INSTANCE TO ZABBIX;
GRANT SELECT ON DBA_USERS TO ZABBIX;
GRANT SELECT ON V_$LOG_HISTORY TO ZABBIX;
GRANT SELECT ON V_$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;
如果是oracle11g用户还需要开放ACL访问控制
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;
可以运行下面的语句确保上面的没有问题
select utl_inaddr.get_host_name('127.0.0.1') from dual;
2.4 创建配置文件config.props
cd /opt/orabbix/conf/
cp /opt/orabbix/conf/config.props.sample config.props
配置参数
# cat config.props|grep -v '^#|^$'
#comma separed list of Zabbix servers
ZabbixServerList=ZabbixServer1
ZabbixServer1.Address=192.168.0.95
ZabbixServer1.Port=10051
#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=oracledb
#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
oracledb.Url=jdbc:oracle:thin:@192.168.0.92:1521:dbsrv1
oracledb.User=zabbix
oracledb.Password=zabbix
#Those values are optionals if not specified Orabbix is going to use the general values
oracledb.MaxActive=10
oracledb.MaxWait=100
oracledb.MaxIdle=1
oracledb.QueryListFile=./conf/query.props
PS：
DatabaseList中放的是被监控的数据库主机名，该名称要和zabbix server界面中的机器名称保持一致
2.5 启动orabbix
# service orabbix start
Starting Orabbix service:
查看启动的进程
# ps aux |grep orabbix
root 25572 35.02.3 1295872 45084 pts/2 Sl 15:54 0:00 /usr/java/jdk1.7.0_80/bin/java -Duser.language=en -Duser.country=US -Dlog4j.configuration=./conf/log4j.properties -cp lib/commons-codec-1.4.jar:lib/commons-dbcp-1.4.jar:lib/commons-lang-2.5.jar:lib/commons-logging-1.1.1.jar:lib/commons-pool-1.5.4.jar:lib/hsqldb.jar:lib/log4j-1.2.15.jar:lib/ojdbc6.jar:.:./orabbix-1.2.3.jar com.smartmarmot.orabbix.bootstrap start ./conf/config.props
root 255850.00.0 103316 844 pts/2 S+ 15:54 0:00 grep orabbix
3. WEB界面配置
3.1导入模板文件
导入模板。模板在/opt/orabbix/template.
Orabbix_export_full.xml 全部导入(图表 监控项 触发器)
Orabbix_export_graphs.xml 图表
Orabbix_export_items.xml 监控项
Orabbix_export_triggers.xml 触发器
模板-->导入
如果导入失败，需要将orabbix的4个xml里面的<group>TEMPLATES</group>改成<group>TEMPLATES_ORACLE</group>，然后重新导入import即可。
3.2 将被监控的主机关联模板
你会发现有一些监控项dbfilesize,dbsize没有值，这是因为/opt/orabbix/conf/query.props文件没有把这两个加入进查询的List下面，可以从query.props.sample把这两项复制进去
在QueryList最后面加上dbfilesize,dbsize
然后在文件末尾加入：
dbfilesize.Query=select to_char(sum(bytes/1024/1024/10), 'FM99999999999999990') retvalue from dba_data_files
dbsize.Query=SELECT to_char(sum( NVL(a.bytes/1024/1024/10 - NVL(f.bytes/1024/1024/10, 0), 0)), 'FM99999999999999990') retvalue \
FROM sys.dba_tablespaces d, \
(select tablespace_name, sum(bytes) bytes from dba_data_files group by tablespace_name) a, \
(select tablespace_name, sum(bytes) bytes from dba_free_space group by tablespace_name) f \
WHERE d.tablespace_name = a.tablespace_name(+) AND d.tablespace_name = f.tablespace_name(+) \
AND NOT (d.extent_management like 'LOCAL' AND d.contents like 'TEMPORARY')
