Title: throw unknown state if no data is returned or url has errors

If a metric does not exist or the URL has error, the check exists with errocode 1 , putting it in warning state. This pull request fixes it to return the unknown state to show it correctly in nagios.

FYI: The way I noticed is was that the status information was set to 'null' and the service got into a warning state. This was due to an incorrect use of a variable in nagios.
