Consider deprecating old api API

**Feature request**
It would be great to have monitoring for api.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_monitoring` with default `false`.

Start by clarifying which old API is meant and what “monitoring for api” should cover in production deployments. Then locate the configuration entry point for a new `enable_monitoring` option and identify the relevant monitoring tests or commands; done means the requested behavior is defined and the default-disabled option is covered.
