How many times have you ever looked at a running application and asked yourself: "What the hell is it doing?" Why did it take so long? "At these moments, you might think it would be nice if you built more monitoring capabilities in your application." For example, in a server application, you can view the number and type of tasks queued for processing, the tasks currently being processed, throughput statistics in the past minute or hour, average task p
