When I try running this code, I get:

nagios_test2.rb:10:in `nagios_data': undefined method `intern' for 
nil:NilClass (NoMethodError)
        from nagios_test2.rb:7:in `inject'
        from nagios_test2.rb:7:in `each'
        from nagios_test2.rb:7:in `inject'
        from nagios_test2.rb:7:in `nagios_data'
        from nagios_test2.rb:3:in `map'
        from nagios_test2.rb:3:in `nagios_data'
        from nagios_test2.rb:19


Where does the intern method come from?
