監控windows主機通過snmp或者nsclient++來監控

Nsclient++可以監控windows主機的cpu、內存、磁盤空間、進程、服務

Nsclient++也支持nrpe所以也可以通過nrpe來監控

NSCA主動與nagios發送檢測，nagios端也需要NSCA daemon

通常使用check_nt，也是最簡單，功能最少的。

安裝NSClient

Allowed hosts：

Nagios所在的主機地址，我這里是192.168.102.128

Password：密碼

是否允許常見插件

是否允許check_nt

是否允許check_nrpe

關閉防火墻之后

上圖為安裝之后查看端口，12489監控0.0.0.0，即check_nt與nsclient++通信的端口

5666為nrpe所使用的端口

想要nagios監控windows

要安裝check_nt

[[email protected]]# cd /usr/local/nagios/libexec/

[root@localhostlibexec]#ls

[root@localhost libexec]# ./check_nt –h       查看幫助。

[root@localhost libexec]# ./check_nt -H 192.168.102.132（被監控主機ip） -p 12489 -v UPTIME

System Uptime - 0 day(s) 1 hour(s) 35 minute(s)         查看當前windows主機的啟動時間

[root@localhostlibexec]# ./check_nt -H 192.168.102.132 -p 12489 -v CPULOAD -w 80 -c 90 -l5,80,90

CPU Load2% (5 min average) |  '5 min avgLoad'=2%;80;90;0;100

查看當前windows主機的cpu使用情況。

[root@localhostlibexec]# ./check_nt -H 192.168.102.132 -p 12489 -v USEDDISKSPACE -w 80 -c 90-l C

C:\ -total: 14.65 Gb - used: 9.72 Gb (66%) - free 4.93 Gb (34%) | 'C:\ UsedSpace'=9.72Gb;11.72;13.18;0.00;14.65

檢測C盤的利用率

計劃進行監控

[root@localhostobjects]# cd /etc/nagios/objects/

[root@localhostobjects]# ls

commands.cfg  localhost.cfg  switch.cfg    timeperiods.cfg

contacts.cfg  printer.cfg   templates.cfg  windows.cfg

[root@localhost objects]# vim commands.cfg       在個加入新的命令。

definecommand{

    command_name check_nt

    command_line $USER1$/check_nt -H$HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$

}【源文件已經有了】

[root@localhost objects]# vim windows.cfg         定義主機

修改：

可以用vim命令：

.,$s@winserver@winhost@g

.     ,    $s   @winserver   @winhost     @g

當前行最后一行搜索 winserver   用其替換前面   go

【修改主機名，可以不進行修改】

[root@localhost objects]# vim windows.cfg

# Createa service for monitoring the W3SVC service

# Changethe host_name to match the name of the host you defined above

defineservice{

    use           generic-service

    host_name        winhost

    service_description   W3SVC

    check_command      check_nt!SERVICESTATE!-d SHOWALL -lW3SVC

    }

# Createa service for monitoring the Explorer.exe process

# Changethe host_name to match the name of the host you defined above

defineservice{

    use           generic-service

    host_name        winhost

    service_description   Explorer

    check_command      check_nt!PROCSTATE!-d SHOWALL -lExplorer.exe

    }

"windows.cfg" 145L, 4005C                          134,0-1    底端

最后啟用此配置文件：

[root@localhostobjects]# cd ..

[root@localhostnagios]# vim nagios.cfg

# You canspecify individual object config files as shown below:

cfg_file=/etc/nagios/objects/commands.cfg

cfg_file=/etc/nagios/objects/contacts.cfg

cfg_file=/etc/nagios/objects/timeperiods.cfg

cfg_file=/etc/nagios/objects/templates.cfg

cfg_file=/etc/nagios/objects/windows.cfg         添加

重啟之前，檢查語法錯誤。

[root@localhost nagios]# /usr/local/nagios/bin/nagios -v/etc/nagios/nagios.cfg

重啟服務，加載新的配置文件。

最后：

對多臺windows主機進行監控：

#cp windows.cfg winserver.cfg

然后修改ip

再把definegroup的注釋掉

添加到監控計劃中。

重啟服務。
