.. versionadded:: 0.7

The ``nagios`` module has two basic functions: scheduling downtime and toggling alerts for services or hosts. 
All actions require the ``host`` parameter to be given explicitly. In playbooks you can use the ``$inventory_hostname`` variable to refer to the host the playbook is currently running on. 
You can specify multiple services at once by separating them with commas, .e.g., ``services=httpd,nfs,puppet``. 
When specifying what service to handle there is a special service value, *host*, which will handle alerts/downtime for the *host itself*, e.g., ``service=host``. This keyword may not be given with other services at the same time. *Setting alerts/downtime for a host does not affect alerts/downtime for any of the services running on it.* 
When using the ``nagios`` module you will need to specify your nagios server using the ``delegate_to`` parameter.
