No error when service not reachable

[tbaumann]

Hi,

thanks for sharing that test helper.

I guess it makes some sense not to fail hard when one server can't be reached. But on the machine level I think that should be a hard fault.
How can I make the nagios helper throw critical if the service is not reachable (only testing localhost on every machine in that case)
Is there a trick to do that or should I test differently?

Also, I'm no zookeeper expert. Does any of the metrics measured in https://github.com/andreisavu/zookeeper-monitoring/blob/master/nagios/services.cfg monitor something as generic as 'cluster status good/bad'?
