有什么方法可以确认Kafka的消费者属性？

Question

I am trying to confirm that Kafka Consumer config is working correctly. I am setting some consumer property values to non-default values (eg session.timeout.ms, heartbeat.interval.ms). Is there a way to query them and ensure that they have been set to the specific values I define in my properties?

I've searched online, but I can't seem to find any guidance on how to query group controller for these configurations.

The closest approach I found is using kafka-consumer-groups.sh, but that does not provide all the details.

Any ideas?

Thanks for any suggestions!

Some further clarification based on feedback: I do use logging, however I don't think that's what I want to check.

Let me try and clarify a bit further. Let's take session.timeout.ms as an example. That setting is used by the group coordinator to determine if a particular consumer is alive. So I would think the group coordinator (which is a kafka broker) must be aware of this setting server-side. So if I set session timeout to a non-default value, I am wondering if there is a way to query the broker to get this setting. If I use logging, I will get the configuration setting on the object that's created when I created the Kafka consumer. It is not providing me with values from the broker. I hope this clarifies the ask. Please correct me if my understand is wrong.

If you setup logging via log4j or Slf4j, the ConsumerConfig object gets printed out in the application logs and will show all loaded properties

Otherwise, they might be shown in JMX as well, but I'm not too sure
