Is the example wrong ?

About the cluster Event:'message',
is this example wrong ?
When I run the code in my machine, It shows numReqs didn't increase as below:

• Version: v10.12.0
• Platform: macOS High Sierra 10.13.3
• Subsystem:

The example is correct, I suppose, but in order to cause the number to increase, you need to issue an HTTP request on localhost port 8000. I did this by opening another terminal window and running curl http://localhost:8000.

The example could stand to be either clarified in the text or changed to be more obvious and not require HTTP requests. Or maybe both. But I wouldn't say it's wrong as is. Just could stand some improvement. ¯\(ツ)/¯
