Automatically generating messages to drive a flow

This topic describes using the TimeoutNotification node to automatically send a message into a message flow.

Aim

Use the TimeoutNotification node to automatically send a message into a message flow every 10 minutes.

Description of the flow

The diagram shows a TimeoutNotification node automatically generating messages every 10 minutes. A description of the diagram is given in the text.
The diagram shows a TimeoutNotification node automatically generating messages and propagating them every 10 minutes. To get the TimeoutNotification node to automatically generate messages, set the Operation Mode property of the node to automatic and specify a value for the Timeout Interval property. In this example the TimeoutNotification node has the following properties:
  • Operation Mode set to automatic
  • Timeout Interval set to 600

When the broker has started, the TimeoutNotification node sends a message every 10 minutes (600 seconds). This message contains only a properties folder and a LocalEnvironment folder. A Compute node can then process this message to create a more meaningful message.

Refer to the following sample for further details on constructing this type of message flow. You can view samples only when you use the information center that is integrated with the Message Brokers Toolkit.
