nagios监控window主机(上)

一、被监控端--window系统

1）下载NSClient++软件

下载地址: http://exchange.nagios.org/directory/Addons/Monitoring-Agents/NSClient%2B%2B/details

2）NSClient安装

3）关闭防火墙，并查询 12489 和 5666 两个端口的监听状态

二、监控端--linux系统

1）在监控端，通过脚本方式查看被监控端（即window系统）的CPU和C盘使用率

[root@svr5 libexec]# ./check_nt -H 192.168.174.100 -p 12489 -v CPULOAD -w 80 -c 90 -l 5,80,90
CPU Load 50% (5 min average) |   '5 min avg Load'=50%;80;90;0;100          #能看到监控结果,说明之前安装在window上的 NSClient 软件正常工作
[root@svr5 libexec]#

2）修改windows.cfg文件之前，对该文件进行备份

[root@svr5 objects]# cd /usr/local/nagios/etc/objects
[root@svr5 objects]# cp windows.cfg windows.cfg.bak
[root@svr5 objects]#

3）修改windows.cfg 文件（该文件指明了监控哪台主机，以及监控的资源）

这里只是将 windows.cfg 模板文件中的监控主机 IP 地址进行修改 , 该文件中还有很多默认的监控服务。

[root@svr5 objects]# vim windows.cfg

4）在主配置文件（nagios.cfg）中添加监控主机文件

主配置文件: /usr/local/nagios/etc/nagios.cfg

监控主机文件: /usr/local/nagios/etc/objects/****.cfg

[root@svr5 etc]# vim /usr/local/nagios/etc/nagios.cfg

5）检测一下配置文件有没有错误

[root@svr5 etc]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

6）重启nagios服务

[root@svr5 etc]# service nagios restart

Starting nagios: Running configuration check... done.
[root@svr5 etc]#

三、测试监控window主机是否成功

address

四、总结

①、监控多台window主机时，监控端的配置基本都是一致的

②、监控多台window主机时，服务端的操作思路：

a）可以拷贝windows.cfg 文件作为末班进行修改, 文件名可以改为 "IP地址.cfg"(这样命名可以一目了然知道该文件配置的是哪个主机的监控)

b ）修改 ***.cfg 监控主机文件的内容,

define host { ------定义监控哪台主机

host_name -----给该文件的主机命名, 可以使用命名为被监控主机的ip地址

address ---- 指定监控哪个IP 的主机

}

define service { --------定义监控什么内容

use generic-service
host_name winserver
service_description NSClient++ Version
check_command check_nt!CLIENTVERSION
}
