check_oracle_health监控oracle

一、准备工作

1.在数据库上创建用户并赋予权限(DBA配合操作；用户、密码待定；只是监控本机数据库TNS、SID）
CREATE USER nagios IDENTIFIED BY XXXX;
GRANT CREATE SESSIONTO nagios;
GRANT SELECT anydictionary TO nagios;
GRANT SELECT ONV_$SYSSTAT TO nagios;
GRANT SELECT ONV_$INSTANCE TO nagios;
GRANT SELECT ON V_$LOGTO nagios;
GRANT SELECT ONSYS.DBA_DATA_FILES TO nagios;
GRANT SELECT ONSYS.DBA_FREE_SPACE TO nagios;

GRANT SELECT ONsys.dba_tablespaces TO nagios;
GRANT SELECT ONdba_temp_files TO nagios;
GRANT SELECT ONsys.v_$Temp_extent_pool TO nagios;
GRANT SELECT ONsys.v_$TEMP_SPACE_HEADER TO nagios;
GRANT SELECT ONsys.v_$session TO nagios;

2.将nagios加入oinstall组

usermod -a -G oinstall nagios

二、查看被监控是否安装了perl?并且被监控机安装DBI和DBD

1.[root@D-MDB-90 ~]# perl -v

This is perl, v5.10.1 (*) built forx86_64-linux-thread-multi

Perl may be copied only under theterms of either the Artistic License or the

GNU General Public License, which maybe found in the Perl 5 source kit.

Complete documentation for Perl,including FAQ lists, should be found on

this system using "manperl" or "perldoc perl". If you have access to the

Internet, point your browser athttp://www.perl.org/, the Perl Home Page.

2.下载DBI

wgethttp://www.cpan.org/authors/id/T/TI/TIMB/DBI-1.636.tar.gz

3.解压DBI

[root@D-MDB-90 src]#tar zxvf DBI-1.636.tar.gz

4.安装DBI

[root@D-MDB-90 src]# cd DBI-1.636

[root@D-MDB-90 DBI-1.636]# perlMakefile.PL

[root@D-MDB-90 DBI-1.636]# make all

[root@D-MDB-90 DBI-1.636]# make install

5.下载安装DBD-Oracle

[root@D-MDB-90 src]# wget http://mirrors.neusoft.edu.cn/cpan/authors/id/P/PY/PYTHIAN/DBD-Oracle-1.74.tar.gz

[root@D-MDB-90 src]# tar zxvf DBD-Oracle-1.74.tar.gz

[root@D-MDB-90 src]# cd DBD-Oracle-1.74

[root@D-MDB-90DBD-Oracle-1.74]# perl Makefile.PL

6.这里会碰到安装错误

切换到oracle用户：su - oracle

查看ORACLE_HOME路径：echo $ORACLE_HOME

[root@D-MDB-90libexec]# echo $ORACLE_HOME /oracle/app/oracle/products/11.2.0.3/db #记住这条oracle_home环境

7.重新切回root：ctrl+d或su - root设置环境变量[root@D-MDB-90DBD-Oracle-1.74]#exportORACLE_HOME=/oracle/app/oracle/products/11.2.0.3/db

[root@D-MDB-90 DBD-Oracle-1.74]#perl Makefile.PL

[root@D-MDB-90DBD-Oracle-1.74]#make && make install

三、下载安装check_oracle_health

1.[root@D-MDB-90 src]# wgethttps://labs.consol.de/assets/downloads/nagios/check_oracle_health-2.1.3.5.tar.gz

2.[root@D-MDB-90 src]# tar -zxvfcheck_oracle_health-2.1.3.5.tar.gz

3.[root@D-MDB-90 src]#cd check_oracle_health-2.1.3.5

4. ./configure --prefix=/usr/local/nagios--with-nagios-user=nagios --with-nagios-group=nagios--with-mymodules-dir=/usr/local/nagios/libexec --with-mymodules-dyndir=/usr/local/nagios/libexec

5. [root@D-MDB-90 src]make all

6.[root@D-MDB-90 src]make install

7.chown nagios:nagios/usr/local/nagios/libexec/check_oracle_health

8.chmod 775/usr/local/nagios/libexec/check_oracle_health

四、测试

1.安装完成后执行命令：/usr/local/nagios/libexec/check_oracle_health --connect=oracle_SID --user=oracle用户 --password=oracle用户密码 --mode=connected-users

如果提示错误：如

check_oracle_health监控oracle

解决方法：

[root@D-MDB-90libexec]# ldd /usr/local/lib64/perl5/auto/DBD/Oracle/Oracle.so（安装缺少文件路径找）

发现没有libclntsh.so.11.1

[root@D-MDB-90libexec]# locate libclntsh.so.11.1

check_oracle_health监控oracle

[root@D-MDB-90 libexec]# ln -s /oracle/app/oracle/products/11.2.0.3/db/lib/libclntsh.so.11.1（空格）/lib/libclntsh.so.11.1

[root@D-MDB-90 libexec]# vim /etc/ld.so.conf

添加

include ld.so.conf.d/*.conf

/oracle/app/oracle/products/11.2.0.3/db/lib #这里的路径与libclntsh.so.11.1 的路径有关

[root@D-MDB-90 libexec]# ldconfig

check_oracle_health监控oracle

[root@D-MDB-90 libexec]# ldd/usr/local/lib64/perl5/auto/DBD/Oracle/Oracle.so

check_oracle_health监控oracle

2.[root@D-MDB-90 libexec]#/usr/local/nagios/libexec/check_oracle_health --connect=pomoho --user=nagios --password=oradbmon --mode=tnsping

结果输出OK - connection established to pomoho.

3.修改/usr/local/nagios/etc/nrpe.cfg

在allowed_hosts后加上本机与监控主机的IP

最后加一行command[check_oracle_health]=/usr/local/nagios/libexec/check_oracle_health --connect=oracle_SID --user=oracle用户 --password=oracle用户密码 --mode=tnsping

4.重启nrpe

5./usr/local/nagios/libexec/check_nrpe -H你的被监控机IP地址 -c check_oracle_health

如果结果同样为OK - connectionestablished to pomoho，则OK

五、修改监控主机的/usr/local/nagios/etc/objects/services.cfg

添加

###################XX-XXX-XXcheck_oracle_health#####################################

define service{

host_name XX-XXX-XX

service_description check_oracle_health_tnsping

check_command check_nrpe!check_oracle_health

max_check_attempts 5

normal_check_interval 5

retry_check_interval 2

check_period 24x7

notification_interval 10

notification_period 24x7

notification_options w,u,c,r

contact_groups yunwei

}

检查配置是否正确 /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

重新加载nagios ： service nagios reload
