<div>Notifications work great. </div>

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.

<div>StackTach works with Nova and Glance events currently.</div>

<div>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:</div>

<div>Hi all,<br>
<br>
<br>
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.<br>
<br>
My question is:<br>
<br>
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.<br>
<br>

Thanks<br>
