Version = "other" means you run RabbitMQ 3.x, which is out of community support.

Therefore my response will be as short as possible:

• The default HTTP API and management UI port is not 10672 but 15672 (add 1 before the AMQP 0-9-1, AMQP 1.0 port)
• The management plugin must be enabled or pre-configured first, it is not enabled by default
• We highly recommend using Prometheus and Grafana for metrics
