Notifications work great. Actually StackTach has a web interface where you can watch the notifications coming through in real-time. We're slowing trying to get Ceilometer to have this functionality. StackTach works with Nova and Glance events currently. https://github.com/rackerlabs/stacktach Here is a video of how to use it (and the cmdline interface to it Stacky) http://www.sandywalsh.com/2012/10/debugging-openstack-with-stacktach-and.html And, if you're a roll-your-own kinda guy, I have a bare-bones Olso-based notifier service here you can look at to see how it works: https://github.com/SandyWalsh/amqp_sandbox Feel free to reach out if you have any other questions about it. Notifications are awesome. -S ________________________________ From: openstack learner [openstackleaner at gmail.com] Sent: Friday, October 18, 2013 3:56 PM To: openstack at lists.openstack.org; openstack-dev at lists.openstack.org Subject: [openstack-dev] Does openstack have a notification system that will let us know when a server changes state ? Hi all, I am using the openstack python api. After I boot an instance, I will keep polling the instance status to check if its status changes from BUILD to ACTIVE. My question is: does openstack have a notification system that will let us know when a vm changes state (e.g. goes into ACTIVE state)? then we won't have to keep on polling it when we need to know the change of the machine state.
