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. O(services=httpd,nfs,puppet). - When specifying what service to handle there is a special service value, O(host), which will handle alerts/downtime/acknowledge for the I(host itself), for example O(services=host). This keyword may not be given with other services at the same time. B(Setting alerts/downtime/acknowledge for a host does not affect alerts/downtime/acknowledge for any of the services running on it.)
