.The `user_agent` ingest processor's `ecs` parameter has no effect.
[%collapsible]
====
*Details* +
In 7.2, we deprecated the `ecs` parameter for the `user_agent` ingest processor.
In 8.x, the `user_agent` ingest processor will only return {ecs-ref}[Elastic
Common Schema (ECS)] fields, regardless of the `ecs` value.

*Impact* +
To avoid deprecation warnings, remove the parameter from your ingest pipelines.
If a pipeline specifies an `ecs` value, the value is ignored.
