Orabbix监控Oracle 11g

Orabbix简介说明

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:

  • 数据库版本
  • 归档文件
  • 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)
  • HitRatio(监控Hit Ratio的触发,表/存储过程,SQLArea,Body)
  • 逻辑I/O(当前读操作,持续的读操作,块的更改)
  • PGA
  • SGA(固定的缓冲,JAVApool,Large Pool,Log Buffer,Shared Pool,Buffer Cache)
  • 物理I/O(重写操作,数据文件写操作,数据文件读操作)
  • SharePool(PoolDictionary Cache, Pool Free Memory, Library Cache,Sql Area ,Misc.)
  • Pin Hit Ratio(monitor Hit Ratio on Trigger, Tables/Procedures, SQLArea,Body)
  • Session/Processes(monitor Sessions and processes)
  • Session (ActiveSession, Inactive Sessions, System Session)

环境

Oracle Server: 192.168.88.53:1521:orcl
Zabbix Server: 192.168.88.56:10050
Zabbix Agent: 192.168.88.56:10051
Orabbix: 192.168.88.56
jdk 1.8: 192.168.88.56

1,下载并安装jdk8

如果已经安装了java,这步可以跳过。

下载地址

http://www.oracle.com/technetwork/java/javase/downloads/index.html

解压安装,这里以jdk-8u152-linux-x64版本为例

mkdir -p /usr/local/java
tar -zxvf jdk-8u152-linux-x64.tar.gz -C /usr/local/java

2,创建oracle监控帐号,在oracle的sqlplus窗口里面执行:

CREATE  USER ZABBIX_MONITOR IDENTIFIED BY zabbix456
DEFAULT TABLESPACE USERS
TEMPORARY TABLESPACE TEMP
PROFILE DEFAULT
ACCOUNT UNLOCK;

GRANT CONNECT TO ZABBIX_MONITOR;
GRANT RESOURCE TO ZABBIX_MONITOR;
ALTER USER ZABBIX_MONITOR DEFAULT ROLE ALL;

GRANT SELECT ANY TABLE TO ZABBIX_MONITOR;
GRANT CREATE SESSION TO ZABBIX_MONITOR;
GRANT SELECT ANY DICTIONARY TO ZABBIX_MONITOR;
GRANT UNLIMITED TABLESPACE TO ZABBIX_MONITOR;
GRANT SELECT ANY DICTIONARY TO ZABBIX_MONITOR;

if you need an User (ZABBIX) for Orabbix with the minimum grants available

GRANT ALTER SESSION TO ZABBIX_MONITOR;
GRANT CREATE SESSION TO ZABBIX_MONITOR;
GRANT CONNECT TO ZABBIX_MONITOR;
ALTER USER ZABBIX_MONITOR DEFAULT ROLE ALL;
GRANT SELECT ON V_$INSTANCE TO ZABBIX_MONITOR;
GRANT SELECT ON DBA_USERS TO ZABBIX_MONITOR;
GRANT SELECT ON V_$LOG_HISTORY TO ZABBIX_MONITOR;
GRANT SELECT ON V_$PARAMETER TO ZABBIX_MONITOR;
GRANT SELECT ON SYS.DBA_AUDIT_SESSION TO ZABBIX_MONITOR;
GRANT SELECT ON V_$LOCK TO ZABBIX_MONITOR;
GRANT SELECT ON DBA_REGISTRY TO ZABBIX_MONITOR;
GRANT SELECT ON V_$LIBRARYCACHE TO ZABBIX_MONITOR;
GRANT SELECT ON V_$SYSSTAT TO ZABBIX_MONITOR;
GRANT SELECT ON V_$PARAMETER TO ZABBIX_MONITOR;
GRANT SELECT ON V_$LATCH TO ZABBIX_MONITOR;
GRANT SELECT ON V_$PGASTAT TO ZABBIX_MONITOR;
GRANT SELECT ON V_$SGASTAT TO ZABBIX_MONITOR;
GRANT SELECT ON V_$LIBRARYCACHE TO ZABBIX_MONITOR;
GRANT SELECT ON V_$PROCESS TO ZABBIX_MONITOR;
GRANT SELECT ON DBA_DATA_FILES TO ZABBIX_MONITOR;
GRANT SELECT ON DBA_TEMP_FILES TO ZABBIX_MONITOR;
GRANT SELECT ON DBA_FREE_SPACE TO ZABBIX_MONITOR;
GRANT SELECT ON V_$SYSTEM_EVENT TO ZABBIX_MONITOR;

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。注意如果创建的账号是小写,以下的ZABBIX_MONITOR需要大写。最好还是大写吧。

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

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

commit;

3,安装部署orabbix

其实orabbix只需要安装在一台服务器即可,我就选择安装在Zabbix Server上,当然上面的jdk是为orabbix服务的,因为orabbix就是一个oracle客户端去查找oracle中的数据,然后传给zabbix,安装orabbix:

下载:

mkdir -p /usr/local/orabbix
cd /usr/local/orabbix
wget  http://nchc.dl.sourceforge.net/project/orabbix/orabbix-1.2.3.zip

安装:

unzip orabbix-1.2.3.zip 
chmod +x run.sh
cp init.d/orabbix /etc/init.d/
chmod +x /etc/init.d/orabbix
sed -i 's#/opt/orabbix#/usr/local/orabbix#g'  /etc/init.d/orabbix
# 根据实际java路径修改
sed -i 's#java#/usr/local/java/jdk1.8.0_152/bin/java#g'  /usr/local/orabbix/run.sh

4,配置config. Props:

orabbix所有的配置文件都在conf目录中,需要将默认的配置文件config.props.sample复制一份后再进行修改和配置。

cd /usr/local/orabbix/conf
cp config.props.sample config.props
vim config.props

以下是修改后和去注释后的配置

ZabbixServerList=ZabbixServer1

ZabbixServer1.Address=192.168.88.56
ZabbixServer1.Port=10051

OrabbixDaemon.PidFile=./logs/orabbix.pid
OrabbixDaemon.Sleep=300
OrabbixDaemon.MaxThreadNumber=100

DatabaseList=testora

DatabaseList.MaxActive=10
DatabaseList.MaxWait=100
DatabaseList.MaxIdle=1

testora.Url=jdbc:oracle:thin:@192.168.88.53:1521:orcl
testora.User=zabbix_monitor
testora.Password=zabbix456
testora.MaxActive=10
testora.MaxWait=100
testora.MaxIdle=1
testora.QueryListFile=./conf/query.props

PS:需要注意的是DatabaseList=testora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。

testora.Url=jdbc:oracle:thin:@192.168.88.53:1521: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192.168.88.53,oracle的端口是1521,orcl指的是数据库的实例名称)

5,启动orabbix服务

启动orabbix

service orabbix start
Starting Orabbix service:

查看启动的orabbix进程

ps aux |grep orabbix

root      1259  0.3  0.6 12112256 203324 pts/1 Sl   16:02   0:13 /usr/local/java/jdk1.8.0_152/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

6,界面导入oracle模版文件

导入时应该注意模板里面的host的name属性,group的属性值是否与zabbix已存在的设置有冲突,如果导入失败,可能是冲突造成的。把这两个属性改一下名即可。
