服務器端安裝：
安裝snmp服務和其他插件服務:
[root@nagios~]# yum -y install net-snmp* #安裝snmp服務。
CPAN安裝：
wgetftp://ftp.monash.edu/pub/cpan/modules/by-category/23_Miscellaneous_Modules/CPAN/CPAN-1.9301.tar.gz
tar-zxf CPAN-1.9301.tar.gz
cdCPAN-1.9301
./configure
make
makeinstall
##該環境必須安裝，在下面編譯nagios-snmp-plugins時會用到。
安裝完成後執行下列操作：
[root@nagioslibexec]# perl -MCPAN -e shell
Terminaldoes not support AddHistory.
cpanshell -- CPAN exploration and modules installation (v1.9301)
ReadLinesupport available (maybe install Bundle::CPAN or Bundle::CPANxxl?)
cpan[1]>install Net::SNMP
#安裝相應的組件，上面是使用install方式進行安裝，如果這種安裝方式不成功，那麼就需要使用下面的編譯方式安裝了。
nagios官方有詳細介紹：
1)By CPAN (best)
oncommand line, as root :
[your_host]# perl -MCPAN -e shell
cpan shell -- CPAN exploration and modules installation (v1.76)
ReadLine support enabled
cpan> install Net::SNMP
Ifit's the first time you run CPAN, it will probably ask you some (simple)questions.
CPANwill also ask you to satisfy some dependencies (Crypt::DES, Digest::MD5,etc..).
2)"By hand"
Getthe folowings modules (tar.gz format) on www.cpan.org #在cpan官網搜索下面的組件，下載安裝。
-Crypt::DES
- Digest::MD5
- Digest::SHA1
- Digest::HMAC
- Net::SNMP
for each one (you must install Net::SNMP at the end) :
tar zxf <module>.tar.gz
cd <module>
perl Makefile.pl
make test
make install
#確保以上相關CPAN的組件全部安裝成功。
安裝nagios-snmp-plugins:
wgethttp://nagios.manubulon.com/nagios-snmp-plugins.1.1.1.tgz
tarzxfv nagios-snmp-plugins.1.1.1.tgz
#解壓後，進入解壓後的目錄
cdnagios_plugins
./install.sh
#根據提示，基本上都回車，安裝。默認就會安裝到/usr/local/nagios/libexec下面。可以通過ls查看，多了很多關於snmp的文件。
[root@nagios~]# ll /usr/local/nagios/libexec/|grep snmp

進行命令檢查：
[root@nagios~]# /usr/local/nagios/libexec/check_snmp_load.pl -H 10.168.0.185 -C 168pop -Tstand -w 80 -c 90 ##檢查被監控端的CPU負載

[root@nagios~]# /usr/local/nagios/libexec/check_snmp_storage.pl -H 10.168.0.185 -C 168pop-m "^Virtual Memory$" -w 70 -c 90 ##檢查虛擬內存使用量
VirtualMemory: 13%used(1551MB/12285MB) (<70%) : OK
添加環境變量
[root@localhostlibexec]#vi /usr/local/nagios/etc/resource.cfg

打開windows主機配置文件：
[root@nagiosetc]# vi nagios.cfg

以下爲實際環境中nagios服務中監控windows的操作：
首先更改命令模板：
[root@nagiosobjects]# cat commands.cfg
###############################################################################
#COMMANDS.CFG - SAMPLE COMMAND DEFINITIONS FOR NAGIOS 3.2.0

command_line /usr/local/nagios/libexec/process_perfdata.pl
}

}
然後更改windows主機服務文件：
[root@nagiosobjects]# cat windows.cfg
###############################################################################
#WINDOWS.CFG - SAMPLE CONFIG FILE FOR MONITORING A WINDOWS MACHINE

}
配置完成後進行配置文件檢查並重啓服務：
/usr/local/nagios/bin/nagios–v/usr/local/nagios/etc/nagios.cfg
servicenagios reload
問題總結：
1，Argument "v6.0.1" isn't numeric in numeric lt (<)
關於:
Argument "v6.0.1" isn't numeric in numeric lt (<) at/usr/local/nagios/libexec/check_snmp_storage.pl line 407.
出自http://bbs.chinaunix.net/thread-3686728-1-1.html這個報錯;
我在/usr/local/nagios/libexec/check_snmp_storage.pl
文件中的407行做了修改將 "<"操作符替換爲"lt"操作符,如果是">"那麼也應當替換爲"gt"操作符
以上這個問題就解決了
2，nagios+pnp讓windows出圖
