Comment 10 for bug 1533680

Sofiia Andriichenko, the problem that you've described is a completely different problem. From your logs: ceilometer.dispatcher.database [-] Failed to connect to db, purpose event re-try later

This is related to db connection, and doesn't have anything in common with HA proxy.

So, I close this bug as fix committed (as it was before). Please open new bug if needed.
