如何使负载警报静音？

在构成我们的 Nagios 服务器的大量文件中，有服务检查负载：

define service{
        use                             generic-service
        name                            check-load
        hostgroup_name                  nrpe-hosts,!webnodes,!build-cluster
        notification_options            c,r
        service_description             NRPE - Load
        check_command                   check_nrpe!check_load
        contacts                        irc
}

还有两个联系人：

define contact{
        contact_name                    irc
        alias                           ircbot
        host_notification_period        24x7
        service_notification_period     24x7
        host_notification_options       d,u,r,f
        service_notification_options    w,u,c,r,f
        service_notification_commands   notify-by-epager
        host_notification_commands      host-notify-by-epager
        pager                           [email protected]
        }

define contact {
       contact_name                             pagerduty
       alias                                    PagerDuty Pseudo-Contact
       service_notification_period              24x7
       host_notification_period                 24x7
       service_notification_options             u,c,r
       host_notification_options                d,r
       service_notification_commands            notify-service-by-pagerduty
       host_notification_commands               notify-host-by-pagerduty
       pager                                    lol-no
}

编辑：还有，服务继承的事情：

define service{
        name                            generic-service
        check_period                    24x7
        max_check_attempts              3
        normal_check_interval           3
        retry_check_interval            1
        notification_interval           0
        notification_period             24x7
        notification_options            w,c,r
        register                        0       ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!
}

Edit2：还有一个通知命令定义，仅供怀疑者使用；）：

# 'notify-by-epager' command definition
define command{
        command_name    notify-by-epager
        command_line    /usr/bin/printf "%b" "Service: $SERVICEDESC$\nHost: $HOSTNAME$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\nInfo: $SERVICEOUTPUT$\nDate: $LONGDATETIME$" | /bin/mail -s "$NOTIFICATIONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$" $CONTACTPAGER$
}

Edit3：和主机定义：

define host{
        host_name                       vmprod1
        alias                           vmprod1.example.com
        address                         192.1.1.123
        use                             generic-host
        hostgroups                      nrpe-hosts,vm-hosts,vm-prod,dellraid-hosts
        contact_groups                  example,example-pager
}

这是服务描述“NRPE - 加载”的唯一检查。根据我的阅读，这应该只提醒 irc 联系人，而不是 pagerduty 联系人。然而，我上个月在 PagerDuty 中收到了 100 多个“NRPE - 加载”警报。

我错过了什么？
