1.安裝NSClient++

訪問http://nsclient.org/nscp/下載NSClient++，這里我使用的是NSClient++-0.3.9-x64的msi安裝包。下載之后直接安裝，過程中會提示輸入Nagios監(jiān)控服務器地址和密碼。地址填寫正確，密碼不用設置。Nagios監(jiān)控服務器事先在監(jiān)控Linux服務器時候已經(jīng)搭建好，以后再和大家分享。
安裝如下圖所示：

2.配置NSClient++

編輯安裝目錄下的NES.ini文件，打開NSClient++的端口。方法為找到：
[NSClient]
;port=12489
去掉port前的“;”就可以啟用12489端口。

我的是安裝在服務器的program files下的NSClient++-Win32-0.3.9目錄中。在cmd中執(zhí)行：
cd C:\Program files\NSClient++-Win32-0.3.5
netstat -an | more
查看12489端口是否正常監(jiān)聽在。
因為安裝時候需要的模塊已經(jīng)勾選了，所以配置文件中不用再作設置。否則可以通過去掉每個模塊前的;來啟用該模塊。

到這里即完成了Windows Server 2008上的配置。接下來我們設置Nagios監(jiān)控服務器。

3.Nagios監(jiān)控服務器設置

vi /usr/local/nagios/etc/nagios.cfg
搜索找到：
# Definitions for monitoring a Windows machine
# cfg_file=/usr/local/nagios/etc/objects/windows.cfg
將第二行的#去掉打開Nagios監(jiān)控的Windows模塊，然后保存。

接著編輯
# vi /usr/local/nagios/etc/objects/windows.cfg
找到并設置監(jiān)控的服務器：
define host{
use windows-server ; Inherit default values from a template
host_name winserver ; The name we're giving to this host
alias My Windows Server ; A longer name associated with the host
address 192.168.0.2 ; IP address of the host
}
設置被監(jiān)控主機名和被監(jiān)控的Windows服務器地址。

接下來搜索各種監(jiān)控的服務并設置：
# Create a service for monitoring the version of NSCLient++ that is installed
# Change the host_name to match the name of the host you defined above

define service{
use generic-service
host_name winserver
service_description NSClient++ Version
check_command check_nt!CLIENTVERSION
}
監(jiān)控NSClient版本。

# Create a service for monitoring the uptime of the server
# Change the host_name to match the name of the host you defined above

define service{
use generic-service
host_name winserver
service_description Uptime
check_command check_nt!UPTIME
}

監(jiān)控服務器在線時間。

# Create a service for monitoring CPU load
# Change the host_name to match the name of the host you defined above

define service{
use generic-service
host_name winserver
service_description CPU Load
check_command check_nt!CPULOAD!-l 20,30,50
}

監(jiān)控服務器CPU負載。

# Create a service for monitoring memory usage
# Change the host_name to match the name of the host you defined above

define service{
use generic-service
host_name winserver
service_description Memory Usage
check_command check_nt!MEMUSE!-w 80 -c 90
}
監(jiān)控服務器的內(nèi)存占用。

# Create a service for monitoring C:\ disk usage
# Change the host_name to match the name of the host you defined above

define service{
use generic-service
host_name winserver
service_description C:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90
}
監(jiān)控系統(tǒng)C盤的磁盤占用。

部署好之后在Nagios中顯示如下：
