Open Stack

If all you want to do is publish a notification you can use oslo.messaging directly. Or, for something lighter weight, we have Notabene, which is a small wrapper on Kombu.

An example of how our notification simulator/generator uses it is available here:
https://github.com/StackTach/notigen/blob/master/bin/event_pump.py

Of course, you'll have to ensure you fabricate a proper event payload.

Hope it helps

Subject: [openstack-dev] [Ceilometer] Generate Event or Notification in Ceilometer

Hi Folks,

Are there any guide or examples to show how to produce a new event or notification add add a handler for this event in ceilometer?

I am asked to implement OpenStack service monitoring which will send an event and trigger the handler once a service, say nova-compute, crashes, in a short time. :(
The link (http://docs.openstack.org/developer/ceilometer/events.html) does a good job on the explanation of concept and hence I know that I need to emit notification to message queue and ceilometer-collector will process them and generate events but it is far from real implementations.

Regards,
Gary
