重新读取配置文件

systemctl reload nagios

notifications_enabled

notifications_enabled允许报警，1表示允许，0表示不允许

在nagios中enable_notifications=1定义了默认允许发送报警信息notifications_enabled是在定义主机配置中对某个服务的定义，如

define service{use                                      local-service         ; Name of service template to usehost_name                          testservice_description             HTTPcheck_command                 check_httpnotifications_enabled           1}
