在Windows中配置Nagios客户端
Nagios需要在Windows上面配置一些信息，之前我直接在配置文件中添加Windows服务器信息，但是发现监控的东西都是一些不痛不痒的，后来按照文档上面说的，发现这回监控的不错，功能很强大。
下面是具体的步骤以及解决办法
首先安装服务器所必须的安装包：
apt-get install nagios-images nagios-nrpe-plugin nagios-nrpe-server nagios-plugins nagios-plugins-basic nagios-plugins-standard nagios3 nagios3-cgi nagios3-common nagios3-core
如果这些都安装好了就进行下一步
编辑 /etc/nagios-plugins/config/nt.cfg 修改里面的文件
把以下的文件
define command {
command_name check_nt
command_line /usr/lib/nagios/plugins/check_nt -H '$HOSTADDRESS$' -v '$ARG1$' }
修改为
define command {
command_name check_nt
command_line /usr/lib/nagios/plugins/check_nt -H '$HOSTADDRESS$' -p 12489 -v $ARG1$ $ARG2$
}
再定义nrpe服务，将信任的 主机加到该文件里
vim /etc/nagios/nrpe.cfg
allowed_hosts=127.0.0.1
In order to allow more hosts to report to the nagios nrpe daemon, change the value to let's say:
allowed_hosts=127.0.0.1,192.168.1.4,192.168.1.5,192.168.1.6
This config allows the three IPs 192.168.1.4-6 to be able to report for nrpe.
For the changes to nrpe server to take effect, it has to be restrarted.
debian:~# /etc/init.d/nagios-nrpe-server restart
然后再在Windows服务器安装nsclient++
之前我安装的时候输入了密码，所以会出现下面的问题
在为windows客户端做监控的过程中，Nagios报 "NSClient - ERROR: Invalid password"的错误，status为UNKOWN，这错误说的是NSClient的密码不可用。
原因如下：
A.在安装Windows客户端程序NSClient++-的时候设置了密码，在nagios 的配置文件没增加-s PASSWORD造成的。
B.在nagios 的配置文件确定不用-s PASSWORD的时候，不小心设置了密码，或者操作失误输入了密码。
解决办法：
1.对于A的情况，在nagios 的配置文件没增加-s PASSWORD，重启nagios 服务。
2.对于B的情况, 在windows客户端，打开C:\Program Files\NSClient++\NSC.ini文件，不password那行注释掉，然后重启动NSClient++ 服务。
切记，咱安装这个的时候最好不要输入密码，否则还要再在服务器端重新配置
在Windows中安装完这个软件后需要重新启动该服务
配置Ubuntu服务器端监控Windows的配置文件
按照官方文档说将这个目录下的文件
/usr/share/doc/nagios3-common/examples/template-object/windows.cfg
直接拷贝到 /etc/nagios3/conf.d 当作监控的脚本
下面的代码是Windows.cfg，根据你自己的需求更改一些配置
PS：前提要在你主机的hosts文件里面加入相关windows服务器的信息
将以上的代码填写到之前的配置文件中
下面是监控windows的配置文件详细信息
