------------------------------------
Hi [~ihavenoem...@163.com] - Have you tried using client-side JMX metrics?
Metrics such as `connection-count` should give you a pretty good sense of the
active network connections. Would something like this help in this situation?
{code:java}
consumer.metrics().get(new MetricName("connection-count" ... )){code}
> Consumer should be able to detect network problem

> Key: KAFKA-15686
> URL: https://issues.apache.org/jira/browse/KAFKA-15686
> Project: Kafka
> Issue Type: New Feature
> Components: consumer
> Affects Versions: 3.5.0
> Reporter: Jiahongchao
> Priority: Minor
>
> When we call poll method in consumer, it will return normally even if some
> partitions do not have a leader.
> What should we do to detect such failures? Currently we have to check log to
> find out broker connection problem.
