15672 RabbitMQ-Management TCP
Reference for TCP port 15672, commonly associated with RabbitMQ-Management.
What it's for
Port 15672 is the default port for RabbitMQ's management plugin — a web-based dashboard (and HTTP API) for monitoring queues, exchanges, connections, and overall broker health. It's a separate concern from the actual AMQP messaging traffic on port 5672; this is purely the operational/administrative interface.
Protocol basics
Unlike the binary AMQP protocol on 5672, port 15672 serves a standard HTTP interface — both a browser-friendly dashboard and a REST API that tools and scripts can query for metrics or perform administrative actions (creating queues, managing users, purging messages). Because it grants administrative visibility and control over the broker, this port should be treated with the same access-control seriousness as 5672 itself — it's not meant for public exposure, and should sit behind authentication and, ideally, network-level restrictions.
