zabbix3.4.6之监控Oracle

Posted 2020-11-01 hyc-blog

　　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

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，将这些模板挪到本地机器上，然后登陆zabbix，把模板导入进去，就可以配置机器了。
