RabbitMQ队列大小没有Spring？ （Java API）

Question

I'm using the Java client with RabbitMQ. I've seen references to finding queue size with a Spring plugin, but I'm not using Spring. Is there a non-Spring way to get the size of a queue given its name? Right now I'm just exec'ing shell commands 'rabbitmqctl list_queues' and parsing the results--not great.

Answer 1

you can enable the http management plugin ,

rabbitmq-plugins enable rabbitmq_management

then use the http API .

If you execute an http call like:

http://your_server/api/queues/your_virtual_host/yourqueue

you have all information about the queue, the output is a json like:

  ... "backing_queue_status": {
    "q1": 0,
    "q2": 0,
    "delta": [
      "delta",
      0,
      0,
      0
    ],
    "q3": 0,
    "q4": 0,
    "len": 0,
    "target_ram_count": 0,
    "next_seq_id": 0,
    "avg_ingress_rate": 0,
    "avg_egress_rate": 0,
    "avg_ack_ingress_rate": 0,
    "avg_ack_egress_rate": 0,
    "mirror_seen": 0,
    "mirror_senders": 0
  },
  "incoming": [],
  "deliveries": [],
  "consumer_details": [],
  "name": "myqueue",
  "vhost": "vhost",
  "durable": true,
  "auto_delete": false,
  "arguments": {},
  "node": "rabbit@lemur01"
}
