The old-fashioned way would be to have a hook in place when an AWS EC2 instance is changing its state from stopped to running. That hook could generate a new Icinga 2 host configuration file and trigger a daemon reload. In terms of services the apply rules come in handy - let the host have some custom attributes provided by tags of your EC2 instance, and create static apply rules matching them. If you prefer to create hosts purely at runtime you may use the /v1/objects/hosts API endpoint in Icinga 2. That requires some sort of automation or integration into existing management tools though. E.g. Foreman provisioning your instance and then pushing the information towards Icinga 2. There are some examples floating around. I’ve created a simple demo for my API talks at Icinga Camps which can be found over here: https://github.com/Icinga/icinga2-api-examples/tree/master/aws-ec2 Kind regards, Michael -- Michael Friedrich, DI (FH) Senior Developer NETWAYS GmbH | Deutschherrnstr. 15-19 | D-90429 Nuernberg Tel: +49 911 92885-0 | Fax: +49 911 92885-77 CEO: Julian Hein, Bernd Erk | AG Nuernberg HRB18461 http://www.netways.de | michael.friedr...@netways.de ** OSBConf 2016 - September - osbconf.org ** ** OSMC 2016 - November - netways.de/osmc ** _______________________________________________ icinga-users mailing list icinga-users@lists.icinga.org https://lists.icinga.org/mailman/listinfo/icinga-users
