Example

Let's say we want to accumulate the values of a couple of fields (port and method) in a new one.

1

Add the Accumulator Action to your Pipeline and link it to your required Listener.

2

Now, double-click the Accumulator Action to configure it. You need to set the following config:

Parameter	Description
Fields list	We add the fields whose values we want to accumulate: port and method.
Accumulate type	Choose By number of events.
Number of events	We want to add a couple of results to our field so we enter 2.
Output	This is the name of the new field that will store the accumulated event. We'll call it accValues.

3

Now link the Default output port of the Action to the input port of your Data sink.

4

Finally, click Publish and choose which clusters you want to publish the Pipeline in.

5

Click Test pipeline at the top of the area and choose a specific number of events to test if your data is transformed properly. Click Debug to proceed.

This is how the new field will return for these events:

port -> 12500 / method -> GET

accValues -> 12500, GET, 12500, GET
