如何获得在Celery中侦听特定Que的主机列表？

Question

In my project I have two ques. I would like to know list of all the workers listening to a que. (need a pythonic way of doing this. Celery is running on a different machine and I want the details on other machine.)

Well if you're using rabbitmq as a broker you can do this:

sudo rabbitmqctl list_consumers

To check a specific queue:

lpiner@host:~$ sudo rabbitmqctl list_consumers -p production |  grep queue1
queue1 <rabbit@host1-rabbitmq.2.15149.130>     None5   true    0       []
queue1 <rabbit@host1-rabbitmq.2.15256.130>     None4   true    0       []
queue1 <rabbit@host1-rabbitmq.2.21562.130>     None4   true    0       []
queue1 <rabbit@host1-rabbitmq.2.21644.130>     None4   true    0       []
queue1 <rabbit@host1-rabbitmq.2.6500.135>      None5   true    0       []
queue1 <rabbit@host2-rabbitmq.2.4028.137>      None10  true    0       []
queue1 <rabbit@host2-rabbitmq.2.4083.137>      None10  true    0       []
queue1 <rabbit@host2-rabbitmq.2.4463.137>      None9   true    0       []
queue1 <rabbit@host2-rabbitmq.2.4497.137>      None10  true    0       []
queue1 <rabbit@host2-rabbitmq.2.6508.137>      None5   true    0       []

You can also use the celery flower UI which is pretty cool. https://flower.readthedocs.io/en/latest/
