zabbix3.4.6之監控Oracle
新zabbix搭建配置完後,公司所有的主機是通過自動註冊完成了添加,網絡設備及其Templates是從舊zabbix中Export出模板,然後Import入新zabbix系統中。一些應用的監控就需要自己重新添加了。
本以為Oracle監控是通過編寫腳本提取出監控的數值,然後再sender到server端進行監控;後來怎麽也找不到舊的監控腳本,咨詢了一下DBA同事,說是Oracle應該有一個特定的zabbix監控插件,百度一下發現了Orabbix插件,那就去看一看官方文檔。
orabbix是需要java運行環境的,所以需要安裝JDK。
添加zabbix用戶
首先在oracle中創建zabbix用戶,可以使用下面腳本;
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,還需要加入下列:
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;
安裝部署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目錄下的orabbix腳本,這個腳本是初始化腳本,不需要此功能就不用改。腳本中orabbix賦為安裝路徑,默認為orabbix=/opt/orabbix,需要改成你安裝的路徑,根據我剛才的部署,所以要改為orabbix=/usr/local/orabbix。
run.sh腳本是一個java命令,如果你的JDK是源碼編譯安裝,這兒就需要將腳本中的java改為指向java的絕對路徑。
配置文件
conf目錄下都是配置文件樣例,需要cp一份再進行配置
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.

配置完成後就可以啟動了
/usr/local/orabbix/run.sh
ps -ef | grep orabbix //查看是否啟動成功
前端配置
/usr/local/orabbix下面有個template目錄,裏面裝的是zabbix模板,將這些模板挪到本地機器上,然後登陸zabbix,把模板導入進去,就可以配置機器了。
