監控windows主機
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
[root@localhostnagios-cn-3.2.0]# 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。

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。
