• zabbix3.4.6之监控Oracle


      新zabbix搭建配置完后,公司所有的主机是通过自动注册完成了添加,网络设备及其Templates是从旧zabbix中Export出模板,然后Import入新zabbix系统中。一些应用的监控就需要自己重新添加了。

      本以为Oracle监控是通过编写脚本提取出监控的数值,然后再sender到server端进行监控;后来怎么也找不到旧的监控脚本,咨询了一下DBA同事,说是Oracle应该有一个特定的zabbix监控插件,百度一下发现了Orabbix插件,那就去看一看官方文档。

      orabbix是需要java运行环境的,所以需要安装JDK。

    添加zabbix用户

    首先在oracle中创建zabbix用户,可以使用下面脚本;

    CREATE USER ZABBIX
    IDENTIFIED BY <REPLACE WITH PASSWORD>
    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_$PARAMETER TO ZABBIX;
    GRANT SELECT ON SYS.DBA_AUDIT_SESSION TO ZABBIX;
    GRANT SELECT ON V_$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;

    如果使用的是oracle11g版本,还需要加入下列:

    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;

     安装部署orabbix

    mkdir /usr/local/orabbix
    cd /usr/local/orabbix
    wget https://jaist.dl.sourceforge.net/project/orabbix/orabbix-1.2.3.zip
    unzip orabbix-1.2.3.zip
    chmod +x
    /usr/local/orabbix/run.sh

      init.d目录下的orabbix脚本,这个脚本是初始化脚本,不需要此功能就不用改。脚本中orabbix赋为安装路径,默认为orabbix=/opt/orabbix,需要改成你安装的路径,根据我刚才的部署,所以要改为orabbix=/usr/local/orabbix。

      run.sh脚本是一个java命令,如果你的JDK是源码编译安装,这儿就需要将脚本中的java改为指向java的绝对路径。

    配置文件  

    conf目录下都是配置文件样例,需要cp一份再进行配置

    cp /user/local/orabbix/conf/config.props.sample /user/local/orabbix/conf/config.props
    #comma separed list of Zabbix servers
    ZabbixServerList=zabbix_server
    
    ZabbixServer1.Address=172.85.10.51
    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=172.87.100.11,172.87.100.12
    
    #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
    DB1.Url=jdbc:oracle:thin:@server.domain.example.com:<LISTENER_PORT>:DB1
    DB1.User=zabbix
    DB1.Password=zabbix_password
    #Those values are optionals if not specified Orabbix is going to use the general values
    DB1.MaxActive=10
    DB1.MaxWait=100
    DB1.MaxIdle=1
    DB1.QueryListFile=./conf/query.props
    
    #pay1
    172.87.100.11.Url=jdbc:oracle:thin:@172.87.100.11:1521:pay1
    172.87.100.11.User=zabbix_oracle_user
    172.87.100.11.Password=zabbix_oracle_passwd
    #
    172.87.100.11.MaxActive=10
    172.87.100.11.MaxWait=100
    172.87.100.11.MaxIdle=1
    172.87.100.11.QueryListFile=./conf/query.props
    
    #pay2
    172.87.100.12.Url=jdbc:oracle:thin:@172.87.100.12:1521:pay2
    172.87.100.12.User=zabbix_oracle_user
    172.87.100.12.Password=zabbix_oracle_passwd
    #
    172.87.100.12.MaxActive=10
    172.87.100.12.MaxWait=100
    172.87.100.12.MaxIdle=1
    172.87.100.12.QueryListFile=./conf/query.props

    PS:

      需要注意的是DatabaseList=DB1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。

      DB1.Url=jdbc:oracle:thin:@172.87.100.11:1521:pay1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172.87.100.11,oracle的端口是1521,pay1指的是数据库的实例名称。

    配置完成后就可以启动了

      /usr/local/orabbix/run.sh

      ps -ef | grep orabbix  //查看是否启动成功

    前端配置

      /usr/local/orabbix下面有个template目录,里面装的是zabbix模板,将这些模板copy到本地机器上,然后登陆zabbix,把模板导入进去,就可以配置机器了。
