Hi, Balázs I have the same scenario with you. AFAIK, notifications in Nova does not support some thing like service enable/disable action. These APIs do nothing more than saving new value to database. But I believe supporting these kind of notifications will not be very complicated.
To the second question, exactly yes. You can get inspiration from OpenStack Ceilometer, stacktach. These project have already listened on OpenStack message bus to get notifications, then do some awesome job. You can find some thing interesting from here ( http://docs.openstack.org/admin-guide-cloud/content/section_telemetry-notifications.html ) 2015-03-30 18:16 GMT+08:00 Balázs Gibizer <balazs.gibi...@ericsson.com>: > Hi, > > I have the following scenario.
