安装snmp服务和其他插件服务:
[root@nagios~]# yum -y install net-snmp* #安装snmp服务。
CPAN安装：
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
##该环境必须安装，在下面编译nagios-snmp-plugins时会用到。
安装完成后执行下列操作：
[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
#安装相应的组件，上面是使用install方式进行安装，如果这种安装方式不成功，那么就需要使用下面的编译方式安装了。
nagios官方有详细介绍：
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) onwww.cpan.org #在cpan官网搜索下面的组件，下载安装。
-Crypt::DES
- Digest::MD5
- Digest::SHA1
- Digest::HMAC
- Net::SNMP
for each one (you must install Net::SNMP at the end) :
tar zxf
cd
perl Makefile.pl
make test
make install
#确保以上相关CPAN的组件全部安装成功。
安装nagios-snmp-plugins:
wgethttp://nagios.manubulon.com/nagios-snmp-plugins.1.1.1.tgz
tarzxfv nagios-snmp-plugins.1.1.1.tgz
#解压后，进入解压后的目录
cdnagios_plugins
./install.sh
#根据提示，基本上都回车，安装。默认就会安装到/usr/local/nagios/libexec下面。可以通过ls查看，多了很多关于snmp的文件。
[root@nagios~]# ll /usr/local/nagios/libexec/|grep snmp

进行命令检查：
[root@nagios~]# /usr/local/nagios/libexec/check_snmp_load.pl -H 10.168.0.185 -C 168pop -Tstand -w 80 -c 90 ##检查被监控端的CPU负载
2CPU, average load 0.0% < 80% : OK
[root@nagios~]# /usr/local/nagios/libexec/check_snmp_storage.pl -H 10.168.0.185 -C 168pop-m "^Virtual Memory$" -w 70 -c 90 ##检查虚拟内存使用量
VirtualMemory: 13%used(1551MB/12285MB) (<70%) : OK
添加环境变量
[root@localhostlibexec]#vi /usr/local/nagios/etc/resource.cfg
$USER7$=-C168pop
$USER8$=-Tstand
打开windows主机配置文件：
[root@nagiosetc]# vi nagios.cfg

以下为实际环境中nagios服务中监控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
#

# understand.
#
#process-host-perfdatacommand definition
definecommand {

command_line /usr/local/nagios/libexec/process_perfdata.pl
}
#process-service-perfdatacommand definiton

}
definecommand {

}

define command {

define command {

command_line $USER1$/check_traffic.sh -V 2c -H$HOSTADDRESS$ $USER7$ -I 1 -w 990,1000 -c 1000,1024 -M -b
}
然后更改windows主机服务文件：
[root@nagiosobjects]# cat windows.cfg
###############################################################################
#WINDOWS.CFG - SAMPLE CONFIG FILE FOR MONITORING A WINDOWS MACHINE
#
#Last Modified: 06-13-2007

defineservice{

check_command check_snmp_stor!"^VirtualMemory$"!60!80
}
配置完成后进行配置文件检查并重启服务：
/usr/local/nagios/bin/nagios–v/usr/local/nagios/etc/nagios.cfg
servicenagios reload
问题总结：
1，Argument "v6.0.1" isn't numeric in numeric lt (<)
关于:
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这个报错;
我在/usr/local/nagios/libexec/check_snmp_storage.pl
文件中的407行做了修改将 "<"操作符替换为"lt"操作符,如果是">"那么也应当替换为"gt"操作符
以上这个问题就解决了
2，nagios+pnp让windows出图
