Nagios indicating hosts up even when all services are down

 This one's simple. You don't have a check_command defined. No
check_command, no check, no status change, no anything.

Subject: [Nagios-users] Nagios indicating hosts up even when all
services are down


One of my nagios monitored hosts died recently, with all the services
indicated as critical. However, even while the host was powered down
(and I had it in pieces on my desk for 2 hours), the host status was
still being indicated as up. Status up, status information host assumed
to be up.

I'm using this host template
define host{
        name                            default
        notifications_enabled           1
        event_handler_enabled           1
        flap_detection_enabled          0
        process_perf_data               1
        retain_status_information       1
        retain_nonstatus_information    1
        max_check_attempts              20
        notification_interval           60
        notification_period             24x7
        notification_options            d,u,r
        register                        0
        }

with each host configured like this
define host {
        host_name       blade2
        use             default
        alias           Blade2 PDC
        parents         CNE-12-CS1,CNE-12-CS2,CNE-12-CS3
        address         192.168.41.17
}

Does anyone have any suggestions, or is there more information which
would be useful.
