# Response Output Engine

The Response output engine writes information produced by Media Server to the `process` action response, which you can view using `action=QueueInfo`.

NOTE: Do not use this engine when Media Server might produce a large amount of data. If you process a video or a stream, or output data from tracks that contain a large amount of metadata, the ACI response could become extremely large. This might result in the system running out of resources, or external applications failing to retrieve the response.

This section describes the parameters that you can set in the configuration section for a Response output task.

Configuration Parameter | Description
--- | ---
Input | A comma-separated list of the tracks that you want to output.
Type | The type of output engine to use. Set this parameter to `response`.
