nagios监控的服务状态为什么是CRITICAL
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？日志：/var/log/nagios/nagios.log

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
max_check_attempts 5
normal_check_interval 1
}
