RabbitMQ stores messages within a dedicated, durable, non-exclusive topic exchange.
Log messages and events have separate queues. For Cloudify Manager version 4.4 and above, logs and events are stored in PostgreSQL. You can access the logs and events from the REST API events endpoint and from the Cloudify Management Console.
