[openstack-dev] [Ceilometer] Capturing isolated events

Can ceilometer-gurus advise?

[For Ceilometer/Juno]
Use case:
catch instance creation error notifications with ceilometer.

I tried the notifications as well as metering route, but haven't quite
figured out how to do this --

- Added a notification class to ceilometer
- Noticed that there is a class called "Instance" which already subscribes
to events compute.instance.*, disabled that by removing it from the egg
entry points (setup.cfg)
- Created a pipeline to define a meter for my notifications class.

I noticed that the ceilometer-agent-notification service does not consume
any notifications with above changes. I had to set
store_events=true in ceilometer.conf

Now, ceilometer generates events, but they are generic type.

1. Should I change event_definitions.yaml to store event information in the
format that I want?
2. a way to generate only the event I am interested in, not all by default.
