ngios默认监控第一个磁盘分区，需要在service中定义多个监控项，如：

成都创新互联总部坐落于成都市区，致力网站建设服务有成都网站建设、成都网站制作、网络营销策划、网页设计、网站维护、公众号搭建、微信平台小程序开发、软件开发等为企业提供一整套的信息化建设解决方案。创造真正意义上的网站建设，为互联网品牌在互动行销领域创造价值而不懈努力！

define service {
                service_description                   check_disk3
                max_check_attempts                    3
                check_interval                        1
                retry_interval                        3
                notification_interval                 0
                notification_options                  w,u,c,r,f,s
                notifications_enabled                 1
                check_command                         check_nrpe!check_disk3
                check_period                          24x7
                notification_period                   24x7
                host_name                             AFA_EBS_DB
}
define service {
                service_description                   check_disk4
                max_check_attempts                    3
                check_interval                        1
                retry_interval                        3
                notification_interval                 0
                notification_options                  w,u,c,r,f,s
                notifications_enabled                 1
                check_command                         check_nrpe!check_disk4
                check_period                          24x7
                notification_period                   24x7
                host_name                             AFA_EBS_DB

然后再监控机上配置这些项即可，如：

command[check_disk3]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/emcpowera1
command[check_disk4]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/emcpowerb1
command[check_disk5]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sdb1
command[check_disk6]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/emcpowerc1

分别重启监控端和被监控段的服务即可

效果如下：
