nagios监控windows-创新互联

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

[root@localhostnagios-cn-3.2.0]# cd /usr/local/nagios/libexec/

[root@localhostlibexec]#ls

[root@localhost libexec]# ./check_nt –h       查看帮助。

[root@localhost 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

[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

查看当前windows主机的cpu使用情况。

[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

检测C盘的利用率

计划进行监控

[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】

[root@localhost objects]# vim windows.cfg         定义主机

修改：

可以用vim命令：

.,$s@winserver@winhost@g

.     ,    $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】

[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

最后启用此配置文件：

[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

重启之前，检查语法错误。

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

检查原因是那里重复了。

再进行检测

没有错误。

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。
