Hello, Nadya, Thank you for raising this important question.
why have you refused to use notifications? Yes, notifications not used in 4.0. Main reason was a buggy ceilometer behavior in case with *SQL backend* + notifications: - https://bugs.launchpad.net/ceilometer/havana/+bug/1255107 (seems it was fixed Dec.6) - https://bugs.launchpad.net/ceilometer/+bug/1257908 Perfomance degradation was a minor reason and only assumption. In my opinion we shouldn't merge notifications, until it will work properly with SQL. Notifications work well with MongoDB backend. We plan to merge notifications into 4.1 release. Here is our code: https://github.com/rsokolkov/fuel/commit/e94e1f2b3604e0e03ea20356f6e92ec317f7c7e8 Thank you, Roman S.
