获取RabbitMQ队列中的消息数 [英] Getting number of messages in a RabbitMQ queue
本文介绍了获取RabbitMQ队列中的消息数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我们正在使用 amqplib 来发布/使用消息.我希望能够读取队列中的消息数(理想情况下是已确认和未确认).这将使我能够向管理员用户显示良好的状态图,并检测某个组件是否无法满足负载需求.
We're using amqplib to publish/consume messages. I want to be able to read the number of messages on a queue (ideally both acknowledged and unacknowledged). This will allow me to show a nice status diagram to the admin users and detect if a certain component is not keeping up with the load.
我在amqplib文档中找不到有关读取队列状态的任何信息.
I can't find any information in the amqplib docs about reading queue status.
有人可以指出我正确的方向吗?
Can someone point me in the right direction?
推荐答案
使用pika:
import pika
pika_conn_params = pika.ConnectionParameters(
host='localhost', port=5672,
credentials=pika.credentials.PlainCredentials('guest', 'guest'),
)
connection = pika.BlockingConnection(pika_conn_params)
channel = connection.channel()
queue = channel.queue_declare(
queue="your_queue", durable=True,
exclusive=False, auto_delete=False
)
print(queue.method.message_count)
使用PyRabbit:
from pyrabbit.api import Client
cl = Client('localhost:55672', 'guest', 'guest')
cl.get_messages('example_vhost', 'example_queue')[0]['message_count']
使用HTTP
语法:
curl -i -u user:password http://localhost:15672/api/queues/vhost/queue
示例:
curl -i -u guest:guest http://localhost:15672/api/queues/%2f/celery
注意:默认虚拟主机为/
,需要将其转义为%2f
Note: Default vhost is /
which needs to be escaped as %2f
使用CLI:
$ sudo rabbitmqctl list_queues | grep 'my_queue'
