Hi! Nova can publish notifications on the queue whenever anything important happens. https://wiki.openstack.org/wiki/SystemUsageData Tools like YAGI can consume these events and send them to downstream systems. Or you could use something like StackTach to consume them and expose them via a REST interface. https://github.com/rackerlabs/stacktach http://stacktach.readthedocs.org/en/latest/api.html https://github.com/rackerlabs/yagi Hope it helps! -S ________________________________ From: Narayanan, Krishnaprasad [narayana at uni-mainz.de] Sent: Wednesday, April 16, 2014 12:05 PM To: openstack at lists.openstack.org Subject: [Openstack] VM events from OpenStack Hallo all, I am implementing a system in Java that should get VM related events such as created, deleted, resized and etc from OpenStack. Can I kindly know is there a project that publishes this information via Java REST interface?
