> When diagnosing network issues, it is useful to have a clear picture of which client disconnected from which broker at what time.
> Currently, when the producer receives a NETWORK_EXCEPTION in its responses, it logs the following:
> {code:java}
> [Producer clientId=<CLIENT>] Received invalid metadata error in produce request on partition <partition> due to org.apache.kafka.common.errors.NetworkException: The server disconnected before a response was received.. Going to request metadata update now {code}
> It would be good if we logged additional information regarding the broker/host whose connection was disconnected
