Lab 36. Registering to all events
Expected completion time of this lab: 10 min.
- on your IBM Cloud-based Node-RED, instance, start a flow which subscribes to all events.
- make sure you see the messages appear in the debug tab
modify the flow by inserting a function node with the following code:
var count = flow.get('count')||0; count += 1 flow.set('count',count); msg.payload = count; return msg;
What does the function above do?
How many messages are published per minute to the broker, on that topic?
