Hi Dmitriy,

Thank you very much for your feedback.

Although it looks like MagnetoDB Events & Notifications component has some 
similarities to Ceilometer, it is much narrower scope. We only plan to provide 
immediate and periodic notifications of MagnetoDB table/data item CRUD 
activities based on Oslo Notification. There’s no backend database storing 
them, and no query API for those notifications. They are different from 
Ceilometer metrics and events. In the future when we integrate with Ceilometer, 
the MagnetoDB notifications are fed into Ceilometer to collect Ceilometer 
metrics, and/or generate Ceilometer events. Basically Ceilometer will be a 
consumer of MagnetoDB notifications.

I’ll update the wiki further to define our scope clearer, and possibly drop the 
word "events” to indicate we focus on notifications.

Hi Charles!

It looks like to me that we are duplicating functionality of Ceilometer project.
 Am I wrong? Have you considered Ceilometer integration for monitoring
