注意：Orabbix目前官网最新版本是1.2.3，是不支持Zabbix4.0的，只能支持到Zabbix3.0

简介

What can it monitor?

Orabbix使用Oracle数据库的Java数据库连接器（JDBC），因此不需要安装Oracle客户端。

Below are some examples of what Orabbix is capable of monitoring:

-- 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 size of database really used space and of Filesize)

第一步：在Zabbix Server服务器上安装Java Runtime Environment 6

bash jdk-6u45-linux-x64.bin
mv jdk1.6.0_45/ jdk
cat <<EOF >>/etc/profile
export JAVA_HOME=/home/jdk
export CLASSPATH=.:\${JAVA_HOME}/jre/lib/rt.jar:\${JAVA_HOME}/lib/dt.jar:\${JAVA_HOME}/lib/tools.jar
export PATH=\$PATH:\${JAVA_HOME}/bin
EOF
source /etc/profile

第二步：下载Orabbix并安装

1.在Zabbix Server服务器上下载并安装Orabbix

Steps for Installation

Download Orabbix to your Zabbix Server
On your Zabbix server, unzip Orabbix to: /opt/orabbix
Copy file /opt/orabbix/init.d/orabbix to /etc/init.d/orabbix
Grant execute permissions to the following files:
    /etc/init.d/orabbix
    /opt/orabbix/run.sh

# 1.下载Orabbix到Zabbix Server
wget https://nchc.dl.sourceforge.net/project/orabbix/orabbix-1.2.3.zip

# 2.在Zabbix server解压Orabbix到/opt/orabbix
unzip orabbix-1.2.3.zip -d /opt/orabbix

# 3.Copy file /opt/orabbix/init.d/orabbix to /etc/init.d/orabbix
cp /opt/orabbix/init.d/orabbix /etc/init.d/orabbix

# 4.赋予以下两个文件可执行权限
chmod +x /etc/init.d/orabbix
chmod +x /opt/orabbix/run.sh

2.在需要监控的Oracle服务器上为Orabbix创建ZABBIX用户

1.登录数据库

sqlplus / as sysdba

2.使用官方提供的脚本创建zabbix用户（以下两个脚本任选）

# Create a User (ZABBIX) for Orabbix to access your Oracle Database.
# You can use the following script:
# 为Orabbix创建用户（ZABBIX）以访问Oracle数据库。
# 您可以使用以下脚本：

CREATE USER ZABBIX
-- IDENTIFIED BY <REPLACE WITH PASSWORD>
IDENTIFIED BY xiaoliu
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;

# NOTE if you need an User (ZABBIX) for Orabbix with the minimum grants available
# you can use the following script:
# 注意如果您需要具有可用最小授权的Orabbix用户（ZABBIX）
# 您可以使用以下脚本：

CREATE USER ZABBIX
-- IDENTIFIED BY <REPLACE WITH PASSWORD>
IDENTIFIED BY xiaoliu
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;

3.注意：如果您使用的是Oracle 11g，则需要添加以下内容：

# NOTE : If you are using Oracle 11g, you will need to add the following:

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;

4.您可以通过运行来验证以上内容是否正确：

# You can verify the above is correct by running:
select utl_inaddr.get_host_name('127.0.0.1') from dual;

5.为Zabbix导入模板

# Create a Host entry in Zabbix for the DB Instance/s you are planning to monitor, and import the templates found at: /opt/orabbix/template

登录Zabbix管理页面 - 配置 - 模板 - 导入 - 浏览（将所有模板导入）

6.修改配置文件config.props

注意：这里的DatabaseList的名字要跟Zabbix Server添加的监控主机名字保持一致。

# 需要先用原始模板复制一份，然后修改
cp /opt/orabbix/conf/config.props.sample /opt/orabbix/conf/config.props

# 根据实际情况修改以下几项（Orabbix支持同时监视N个Oracle数据库，这里演示1个的配置文件）
vim /opt/orabbix/conf/config.props

ZabbixServerList=ZabbixServer1
ZabbixServer1.Address=10.0.1.66
ZabbixServer1.Port=10051

DatabaseList=DB1
DB1.Url=jdbc:oracle:thin:@10.0.1.111:1521:oracledb
DB1.User=zabbix
DB1.Password=xiaoliu

7.启动Orabbix

/opt/orabbix/run.sh

8.在Oracle数据库服务器上装agent并启动

# 1.安装agent
rpm -i https://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
yum install -y zabbix-agent

# 2.修改配置文件（根据实际情况修改以下3项，其他可以保持默认）
vim /etc/zabbix/zabbix_agentd.conf

Server=11.11.11.61
ServerActive=11.11.11.61
Hostname=Oracle

# 3.开启并设置开机自动启动
systemctl start zabbix-agent
systemctl enable zabbix-agent
systemctl status zabbix-agent

9.在Zabbix Server添加监控主机

1.增加监控主机
    登录Zabbix管理页面 - 配置 - 主机 - 创建主机
        主机名称：任意
        群组：根据自己实际情况，我这里选的是Linux servers
        agent代理程序的接口
            IP地址：填写Oracle数据库服务器的IP地址
            端口：如果没有修改的话，保持默认的10050即可
    
2.为主机增加监控项
    登录Zabbix管理页面 - 配置 - 主机 - 选择刚添加的主机
        模板 - 选择刚添加的Orabbix模板（Template_Oracle）

10.至此配置完成，登录Zabbix Server管理有页面可以查看Oracle的监控情况。
