It's #1.  Nagios only supports macro expansion for command objects (maybe 
others I don't know).  Using macro expansions will work in the arguments (if 
any) that you pass to the check_command because they're expanded for the 
command object.

Being able to do what you are trying to do here would be nice.  I would like 
to use macros for constructing host and service names.
