[Bug] Issues with Exception Propagation and Handling During Metric Collection

[Rancho-7]

Question

Scenario

In Kafka Clinet Monitor,I didn't start a kafka server localhost,but got a success when detecting the connection.

Question

When collecting metrics using MetricsCollect#run,

If error occurs,we catch the exception and set the response status to fail.

In the first method, preCheck, the exception is thrown and handled correctly.

However, in the second method, collect (e.g., KafkaCollectImpl), exceptions are handled internally by logging the error, but are not propagated to the calling method. As a result, if an exception occurs during this process, we are unable to correctly set the response status.

In this scenario for Kafka,we will get a TimeOutException here

Is it a bug? If so,I would like to help fix and optimize it. :)
