Nagios报警时间间隔的配置
host_name:必须是主机配置文件hosts.cfg中定义的主机。
check_command:在commands.cfg文件中定义或在nrpe.cfg里面定义的命令;
max_check_attempts: 最大重试次数,一般设置为4次左右;
normal_check_interval 和retry_check_interval检查间隔的单位是分钟。
notification_interval 通知间隔指探测到故障后,每隔多长时间发送一次报警信息,单位是分钟。
notification_options:通知选项跟联系人配置文件相同。
contact_groups:配置文件contactgroup.cfg定义的组名称。
注意:check_command选项后面跟的命令一定要在commands.cfg里有定义;

vi /usr/local/nagios/etc/services.cfg
