not sure what version you are using, but basic workflow since mitaka (i think) is the notification agent listens to 'notifications.*' topics on specific exchanges (including) ceilometer. for events, it attempts to match incoming message against known events[1]. it will build event based on definition. if there is no, definition, it will create a sparse event with a few attributes. from there it is processed according to pipeline[2]. you'll noticed by default it pushes to gnocchi so it won't get stored in ceilometer/panko storage. you can edit it accordingly.
