+short_description: Perform common tasks in Nagios related to downtime and notifications. 
+description:
+  - "The Nagios module has two basic functions: scheduling downtime and toggling alerts for services or hosts."
+  - All actions require the C(host) parameter to be given explicitly. In playbooks you can use the C($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., C(services=httpd,nfs,puppet).
+  - When specifying what service to handle there is a special service value, B(host), which will handle alerts/downtime for the B(host itself), e.g., C(service=host). This keyword may not be given with other services at the same time. I(Setting alerts/downtime for a host does not affect alerts/downtime for any of the services running on it.)
+  - When using the B(nagios) module you will need to specify your nagios server using the C(delegate_to) parameter.
