public interface MessageMonitor<T extends Message<?>>

Specifies a mechanism to monitor message processing. When a message is supplied to a message monitor it returns a callback which should be used to notify the message monitor of the result of the processing of the event. For example, a message monitor can track various things like message processing times, failure and success rates and occurred exceptions. It also can gather information contained in messages headers like timestamps and tracers
