监控windows主机
监控windows主机通过snmp或者nsclient++来监控
Nsclient++可以监控windows主机的cpu、内存、磁盘空间、进程、服务
Nsclient++也支持nrpe所以也可以通过nrpe来监控
NSCA主动与nagios发送检测，nagios端也需要NSCA daemon
通常使用check_nt，也是最简单，功能最少的。
安装NSClient
Allowed hosts：
Nagios所在的主机地址，我这里是192.168.102.128
Password：密码
是否允许常见插件
是否允许check_nt
是否允许check_nrpe
关闭防火墙之后
上图为安装之后查看端口，12489监控0.0.0.0，即check_nt与nsclient++通信的端口
5666为nrpe所使用的端口
想要nagios监控windows
要安装check_nt
[[email protected]]# cd /usr/local/nagios/libexec/
[[email protected]]#ls
[[email protected] libexec]# ./check_nt –h 查看帮助。
[[email protected] libexec]# ./check_nt -H 192.168.102.132（被监控主机ip） -p 12489 -v UPTIME
System Uptime - 0 day(s) 1 hour(s) 35 minute(s) 查看当前windows主机的启动时间
[[email protected]]# ./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
查看当前windows主机的cpu使用情况。
[[email protected]]# ./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
检测C盘的利用率
计划进行监控
[[email protected]]# cd /etc/nagios/objects/
[[email protected]]# ls
commands.cfg localhost.cfg switch.cfg timeperiods.cfg
contacts.cfg printer.cfg templates.cfg windows.cfg
[[email protected] objects]# vim commands.cfg 在个加入新的命令。
definecommand{
command_name check_nt
command_line $USER1$/check_nt -H$HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$
}【源文件已经有了】
[[email protected] objects]# vim windows.cfg 定义主机
修改：
可以用vim命令：
.,[email protected]@[email protected]
. , $s @winserver @winhost @g
当前行最后一行搜索 winserver 用其替换前面 go
【修改主机名，可以不进行修改】
[[email protected] 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
最后启用此配置文件：
[[email protected]]# cd ..
[[email protected]]# 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
重启之前，检查语法错误。

检查原因是那里重复了。
再进行检测

没有错误。
[[email protected] nagios]# service nagios restart

重启服务，加载新的配置文件。
最后：
对多台windows主机进行监控：
#cp windows.cfg winserver.cfg
然后修改ip
再把definegroup的注释掉
添加到监控计划中。
重启服务。
