nagios监控的服务状态为什么是CRITICAL

hanyi412

自己在虚拟机上配置nagios，添加了2个服务，check_load及check_disk_sda2，为什么状态显示为CRITICAL？

添加的配置：/etc/nagios/conf.d/192.168.12.120.cfg
define host{
        use                     linux-server
        host_name               192.168.12.120
        alias                   120
        address                 192.168.12.120
        }


define service{
        use                     generic-service
        host_name               192.168.12.120
        service_description     check_http
        check_command           check_http
        max_check_attempts      5
        normal_check_interval 1
}


define service{
        use     generic-service
        host_name       192.168.12.120
        service_description     check_load
        check_command           check_nrpe!check_load
        max_check_attempts 5
        normal_check_interval 1
}


define service{
        use     generic-service
        host_name       192.168.12.120
        service_description     check_disk_sda2
        check_command           check_nrpe!check_sda2
