nagios服务器：192.168.217.131

被监控端：192.168.217.154

vim /usr/local/nagios/etc/objects/hosts.cfg (hosts.cfg新建的)

define host{

       use                       linux-server

       host_name            lamp

       alias                     lamp

       address               192.168.217.154

}

definehostgroup{

       hostgroup_name       lamp-server

       alias                        lamp-server

       members                 lamp

}

vim /usr/local/nagios/etc/objects/services.cfg（service新建的）

define service{

       use                                  local-service

       host_name                       lamp

       service_description           check-host-alive

       check_command              check-host-alive

}

define service{

       use                     local-service,services-pnp

       host_name                lamp

       service_description      PING  //表示监控ping服务

       check_command            check_ping!100.0,20%!500.0,60%

}

define service{

       use                               local-service

       host_name                     lamp

       service_description          SSH

       check_command             check_ssh

}

define service{

       use                                 local-service

       host_name                     lamp

       service_description          Swap Usage

       check_command             check_local_swap!20!10

}

define service{

       use                                local-service

       host_name                     lamp

       service_description         Current Users

       check_command            check_local_users!20!50

}

检查是否配置有问题：/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Total Warnings: 0
Total Errors:   0
看到2个0说明配置没问题：

在vim /usr/local/nagios/etc/nagios.cfg中添加

然后重启nagios服务：

[root@nagios objects]# /etc/init.d/nagios restart
Restarting nagios (via systemctl):                         [  确定  ]
在服务器的浏览器中：http://http://192.168.217.131(服务器ip)/nagios/

需要输入账号和密码，见上篇nagios监控的安装 http://wangjiatong.blog.51cto.com/11834370/1886423

然后就看到这样的效果：
