Service check_commands have always been required. Host check_commands
are optional.

Reading configuration data...

Error: Service description, host name, or check command is NULL

Error: Could not register service (config file
'/usr/local/nagios-db/etc/ena_config/davidson.cfg', line 438)

check_command is red, meaning it's required.

There are several features of nagios that require the check_command to
be present (freshness checking, scheduling immediate checks, etc). You
may not use those but the command is still required. Use check_dummy as
filler.
