Working with the Echo Node

Overview of the Echo Node

You can add an Echo node to a Flow tab in an orchestration job to pass inputs that you specify to outputs. This function helps make jobs more readable.
The Echo node can also be used to gather output values from around the orchestration job into a central place. For example, you could have a series of nodes that output a few values. You can add an echo node to the Flow tab and map several of those outputs into the Echo node. The output of the Echo node will contain the values that you mapped.
Finally, you can use the Echo node as a placeholder in an orchestration job. For example, you could have a loop situation with a logical branch. In this case, you might need both paths from the logical branch to go back to the looping node. You could establish an Echo node as the last node in the loop construct instead of having to draw a line from each of these nodes. Then it would be the only node that loops back to the beginning.

Inputs and Outputs to the Echo Node

You can specify any string as an input on the Input tab. This input is passed to the Output tab.

Using the Echo Node

You can create an orchestration job that uses an Echo node to pass inputs into outputs in the context of the job. For example, a job could include an Echo node that has a bad source binding that generates an error. This error, in turn, is detected by the Event Listener 1 node.
This sample orchestration job is shown in the following display:

The settings for the Echo node are shown in the following display:

Echo Settings
The settings for the Event Listener 1 node are shown in the following display:
Event Listener 1 Settings
Event Listener 1 Settings
Note that all events from the Echo node are listened for by the Event Listener node.
