问题描述
有谁知道是否有办法从客户端应用程序检查 RabbitMQ 队列中的消息数量?
Does anyone know if there's a way to check the number of messages in a RabbitMQ queue from a client application?
我正在使用 .NET 客户端库.
I'm using the .NET client library.
推荐答案
你可以通过客户端实际检索这个.
You can actually retrieve this via the client.
当你执行 queue_declare
操作时,RabbitMQ 返回一个包含三个值的元组:(
.queue_declare
的 passive
参数允许您在不修改服务器状态的情况下检查队列是否存在,因此您可以将 queue_declare
与 一起使用被动
选项来检查队列长度.
When you perform a queue_declare
operation, RabbitMQ returns a tuple with three values: (<queue name>, <message count>, <consumer count>)
. The passive
argument to queue_declare
allows you to check whether a queue exists without modifying the server state, so you can use queue_declare
with the passive
option to check the queue length.
不确定 .NET,但在 Python 中,它看起来像这样:
Not sure about .NET, but in Python, it looks something like this:
name, jobs, consumers = chan.queue_declare(queue=queuename, passive=True)
