nagios监控插件 nagios_oracle_health+check_linux_stats.pl怎么用
这篇文章给大家分享的是有关nagios监控插件 nagios_oracle_health+check_linux_stats.pl怎么用的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
一.安装nagios_oracle_health插件
项目地址：https://labs.consol.de/nagios/check_mysql_health/
1.查看perl包有没有安装。
[root@DB02 ~]# rpm -qa|grep perl
perl-Test-Simple-0.92-136.el6.x86_64
perl-ExtUtils-MakeMaker-6.55-136.el6.x86_64
perl-version-0.77-136.el6.x86_64
perl-ExtUtils-ParseXS-2.2003.0-136.el6.x86_64
perl-libs-5.10.1-136.el6.x86_64
perl-5.10.1-136.el6.x86_64
perl-CGI-3.51-136.el6.x86_64
perl-devel-5.10.1-136.el6.x86_64
perl-Pod-Escapes-1.04-136.el6.x86_64
perl-Pod-Simple-3.13-136.el6.x86_64
perl-Test-Harness-3.17-136.el6.x86_64
perl-Module-Pluggable-3.90-136.el6.x86_64
[root@DB02 ~]# perl -v

从执行上面的两个命令好，可以看到perl包安装正常
2.安装DBI
tar -zxvf DBI-1.636.tar.gz
cd DBI-1.636
perl Makefile.PL
make all
make install
3.安装DBD-Oracle
tar -zxvf DBD-Oracle-1.74.tar.gz
cd DBD-Oracle-1.74
perl Makefile.PL
执行命令报错如下：
[root@DB01 DBD-Oracle-1.74]# perl Makefile.PL
Multiple copies of Driver.xst found in: /usr/local/lib64/perl5/auto/DBI/ /usr/lib64/perl5/auto/DBI/ at Makefile.PL line 39
Using DBI 1.636 (for perl 5.010001 on x86_64-linux-thread-multi) installed in /usr/local/lib64/perl5/auto/DBI/
Configuring DBD::Oracle for perl 5.010001 on linux (x86_64-linux-thread-multi)
Remember to actually *READ* the README file! Especially if you have any problems.
Trying to find an ORACLE_HOME
Your LD_LIBRARY_PATH env var is set to ''
The ORACLE_HOME environment variable is not set and I couldn't guess it.
It must be set to hold the path to an Oracle installation directory
on this machine (or a machine with a compatible architecture).
See the appropriate README file for your OS for more information.
ABORTED!
解决方法：在root的bash_profile里面添加下面的代码#这里是现网的数据库的环境变量的配置
ORACLE_BASE=/u01/oracle/app
ORACLE_HOME=$ORACLE_BASE/product/11g/dbhome_1
ORACLE_SID=kdzfw
LD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin:$ORACLE_HOME/OPatch
export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH PATH
source .bash_profile
重新执行命令perl Makefile.PL
make all
make install
登录数据库，建个nagios帐号，并授予一些权限。
create user nagios identified by oradbmon;grant create session to nagios;grant select any dictionary to nagios;grant select on V_$SYSSTAT to nagios;grant select on V_$INSTANCE to nagios;grant select on V_$LOG to nagios;grant select on SYS.DBA_DATA_FILES to nagios;grant select on SYS.DBA_FREE_SPACE to nagios;
4.安装check_oracle_health
tar -zxvf check_oracle_health-2.1.3.5.tar.gz
cd check_oracle_health-2.1.3.5
./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios --with-mymodules-dir=/usr/local/nagios/libexec --with-mymodules-dyn-dir=/usr/local/nagios/libexec
make all
make install
5.使用oracle用户运行测试脚本：如下的输出说明插件工作正常。
./check_oracle_health --connect=orcl --username=nagios --password= oradbmon --mode=tnsping
OK - connection established to orcl.
6.把oracle下面的环境变量复制到root下的bash_profile里面，并执行source bash_profile使配置立即生效。
7.在被监控机上定义一个服务，监控表空间，在客户机的nrpe.cfg里配置监控命令。
command[check_tablespace]=/usr/local/nagios/libexec/check_oracle_health --connect kdzfw --username nagios --password oradbmon --warning 95 --critical 98 --mode tablespace-usage
注意：把nrpe.cfg配置文件里的dont_blame_nrpe=1，允许命令后可以带一些参数。
使用脚本在本地测试使用脚本监控表空间，显示正常，如下所示：
[oracle@DB01 libexec]$ /usr/local/nagios/libexec/check_oracle_health --connect kdzfw --username nagios --password oradbmon --warning 95 --critical 98 --mode tablespace-usage
OK - tbs VIPC usage is 0.00%, tbs USERS usage is 0.90%, tbs UNDOTBS1 usage is 0.05%, tbs TEMP usage is 0.01%, tbs SYSTEM usage is 2.65%, tbs SYSAUX usage is 2.65%, tbs SPTESTREADER usage is 0.00%, tbs SPTESTIM usage is 0.36%, tbs MAINTAIN usage is 0.05%, tbs INDX usage is 29.67%, tbs BTEST usage is 51.32% | 'tbs_vipc_usage_pct'=0.00%;95;98 'tbs_vipc_usage'=1MB;31129;32112;0;32767 'tbs_vipc_alloc'=1024MB;;;0;32767 'tbs_users_usage_pct'=0.90%;95;98 'tbs_users_usage'=294MB;31129;32112;0;32767 'tbs_users_alloc'=310MB;;;0;32767 'tbs_undotbs1_usage_pct'=0.05%;95;98 'tbs_undotbs1_usage'=16MB;31129;32112;0;32767 'tbs_undotbs1_alloc'=825MB;;;0;32767 'tbs_temp_usage_pct'=0.01%;95;98 'tbs_temp_usage'=2MB;31129;32112;0;32767 'tbs_temp_alloc'=1203MB;;;0;32767 'tbs_system_usage_pct'=2.65%;95;98 'tbs_system_usage'=869MB;31129;32112;0;32767 'tbs_system_alloc'=930MB;;;0;32767 'tbs_sysaux_usage_pct'=2.65%;95;98 'tbs_sysaux_usage'=867MB;31129;32112;0;32767 'tbs_sysaux_alloc'=920MB;;;0;32767 'tbs_sptestreader_usage_pct'=0.00%;95;98 'tbs_sptestreader_usage'=1MB;31129;32112;0;32767 'tbs_sptestreader_alloc'=1024MB;;;0;32767 'tbs_sptestim_usage_pct'=0.36%;95;98 'tbs_sptestim_usage'=119MB;31129;32112;0;32767 'tbs_sptestim_alloc'=1024MB;;;0;32767 'tbs_maintain_usage_pct'=0.05%;95;98 'tbs_maintain_usage'=1MB;1945;2007;0;2048 'tbs_maintain_alloc'=1024MB;;;0;2048 'tbs_indx_usage_pct'=29.67%;95;98 'tbs_indx_usage'=9721MB;31129;32112;0;32767 'tbs_indx_alloc'=11024MB;;;0;32767 'tbs_btest_usage_pct'=51.32%;95;98 'tbs_btest_usage'=50451MB;93388;96337;0;98303 'tbs_btest_alloc'=71680MB;;;0;98303
8.服务端使用的是nagiosql管理工具，在里面配置相应的服务。
9.nagios展示的效果：
二.安装check_linux_stats.pl脚本
1.先安装perl-UNIVERSAL-require-0.13-1.el6.rf.noarch.rpm，这里是rpm包。
[root@DB02 huaxia]# rpm -ivh perl-UNIVERSAL-require-0.13-1.el6.rf.noarch.rpm
warning: perl-UNIVERSAL-require-0.13-1.el6.rf.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY
Preparing... ########################################### [100%]
1:perl-UNIVERSAL-require ########################################### [100%]
[root@DB02 huaxia]# rpm -qa|grep perl-UNIVERSAL-require
perl-UNIVERSAL-require-0.13-1.el6.rf.noarch
2.安装Sys-Statistics-Linux
tar -zxvf Sys-Statistics-Linux-0.66.tar.gz
cd Sys-Statistics-Linux-0.66
[root@DB02 Sys-Statistics-Linux-0.66]# perl Makefile.PL
Checking if your kit is complete...
Looks good
Warning: prerequisite Time::HiRes 0 not found.#报错！
Writing Makefile for Sys::Statistics::Linux
解决方法：yum -y install perl-Time-HiRes
重新执行：
[root@DB02 Sys-Statistics-Linux-0.66]# perl Makefile.PL
Writing Makefile for Sys::Statistics::Linux
make all
make install
3.下载check_linux_stats.pl监控脚本，并把脚本放到/usr/local/nagios/libexec的插件目录里
执行./check_linux_stats.pl，可以看到该脚本可以监控很多参数。
[oracle@DB02 libexec]$ ./check_linux_stats.pl --help
check_linux_stats v1.3.1
Usage: ./check_linux_stats.pl -C|-P|-M|-N|-D|-I|-L|-F|-S|-W|-U -p
-h, --help
print this help message

-M, --memory=MEMORY USAGE
-N, --network=NETWORK USAGE
-D, --disk=DISK USAGE
-I, --io=DISK IO USAGE
-L, --load=LOAD AVERAGE
-F, --file=FILE STATS
-S, --socket=SOCKET STATS

-u, --unit
%, KB, MB or GB left on disk usage, default : MB
REQS OR BYTES on disk io statistics, default : REQS
-V, --version
version number
ex :

Cpu usage : perl check_linux_stats.pl -C -w 90 -c 95 -s 5
Disk usage : perl check_linux_stats.pl -D -w 95 -c 100 -u % -p /tmp,/usr,/var
Load average : perl check_linux_stats.pl -L -w 10,8,5 -c 20,18,15
Paging statistics : perl check_linux_stats.pl -W -w 10,1000 -c 20,2000 -s 3
Process statistics : perl check_linux_stats.pl -P -w 100 -c 200
I/O statistics on disk device : perl check_linux_stats.pl -I -w 10 -c 5 -p sda1,sda4,sda5,sda6
Network usage : perl check_linux_stats.pl -N -w 10000 -c 100000000 -p eth0
Processes virtual memory : perl check_linux_stats.pl -T -w 9551820 -c 9551890 -p /var/run/sendmail.pid
Uptime : perl check_linux_stats.pl -U -w 5
[oracle@DB02 libexec]$ ./check_linux_stats.pl -M -w 90 -c 95#测试了下内存，显示正常。
MEMORY CRITICAL : Mem used: 97.96%, Swap used: 0.96% |MemUsed=97.96%;90;95 SwapUsed=0.96;; MemCached=91.65 SwapCached=0.21 Active=60.85
4.在客户机的nrpe.cfg里面加入几项监控的服务。
command[check_HA_servhamachine]=/usr/local/nagios/libexec/check_procs -w $ARG1$ -c $ARG2$ -C $ARG3$
command[check_linux_stats_root]=/usr/local/nagios/libexec/check_linux_stats.pl -D -w $ARG1$ -c $ARG2$ -p $ARG3$
command[check_linux_stats_load]=/usr/local/nagios/libexec/check_linux_stats.pl -L -w $ARG1$ -c $ARG2$
command[check_linux_stats_cpu]=/usr/local/nagios/libexec/check_linux_stats.pl -C -w $ARG1$ -c $ARG2$ -s $ARG3$
command[check_linux_stats_mem]=/usr/local/nagios/libexec/check_linux_stats.pl -M -w $ARG1$ -c $ARG2$
5.服务器端用的是nagiosql,在里面把这几个监控项加一下。
6.nagios服务端的展示效果。
