Passive Service Checks in Nagios 2.0

[Brian C. Huffman]

All,

I'm trying to setup a passive service check - specifically, I have
syslog-ng / sec combination to monitor system log files and then to
write into the nagios cmd file.  In Nagios 1.2, I didn't need to specify
a check_command (since there isn't one), and even looking at the 2.0
documentation, it doesn't mention a check command:

In Nagios:

      * Configure a service called Port Scans and associate it with the
        host that PortSentry is running on.
      * Set the max_check_attempts option in the service definition to
        1. This will tell Nagios to immediate force the service into a
        hard state when a non-OK state is reported.
      * Either set the active_checks_enabled option to 0 or set the
        check_time option in the service definition to a timeperiod that
        contains no valid time ranges. Doing either of these will
        prevent Nagios from ever actively checking the service. Even
        though the service check will get scheduled, it will never
        actually be checked.

So....why then does nagios -v ./nagios.cfg give me this error:

Error: Service description, host name, or check command is NULL
Error: Could not register service (config file
'/usr/local/nagios2/etc/services.cfg', starting on line 16)

The description and host name do exist, so I can only assume that it
wants a check command...  This doesn't seem to make sense to me for a
passive service.  What's the work around?

Thanks,
Brian
