Hi Natalie,
You might need a 'check_command' for each of your hosts... like this:
check_command check-host-alive
The 'check-host-alive' check command would have to be defined, probably in your commands.cfg file. The default nagios configuration defines this command (I think).
This is where it's handy to use templates -- in this case, a host template. You would define stuff common to every host in your host template (which you might call 'generic-host'), and have a 'use generic-host' line in each of your host definitions. That way, you wouldn't have to redefine the same stuff over and over again for each of your hosts.
It might be worth spending an hour or two reading the official nagios documentation at this point -- it could save you lots of time. The official doc table of contents is at:
http://nagios.sourceforge.net/docs/3_0/toc.html
Cheers,
Guy.
