Hello Jonathan,

I think that you must put 

define service {
         service_description            Oracle
         host_name                      oddjob.resnet.bris.ac.uk
         use                            resnet-service
        max_check_attempts        1
        check_freshness         1
        freshness_threshold     86400

        check_command           check_dummy!1 "no news since 24h"
}
=> The check_dummy command will run if no passive check has been received within 24 hours (86400seconds) and display warnig alert (1)  and info status "no news since 24h"

Regards, 

Mohamed

Objet : [Nagios-users] Defining passive checks
 
I'm a long-time user of Nagios with active checks. Today I started using 
passive checks with NSCA and I'm having a problem.

The documentation states "A service must be defined in Nagios before you 
can submit passive check results for it".

I defined a config block like this, to define a service for the Oracle 
service that I want to monitor passively - omitting the check_command 
directive.

define service {
         service_description            Oracle
         host_name                      oddjob.resnet.bris.ac.uk
         use                            resnet-service
}



But running nagios -v gives this output:

Error: Service description, host name, or check command is NULL
Error: Could not register service (config file 
'/etc/nagios/nagios_service.cfg', starting on line 8618)
    Error processing object config files!


So what's the approved way of defining a service without specifying a 
command for active checks?

Thanks,
Jonathan
