Consider deprecating old data API

**Description**
Currently middleware lacks proper monitoring support.

**Proposed solution**
Add configurable monitoring with sensible defaults.

**Priority**: Low/Medium

The issue names no files, tests, or entry points, and its title conflicts with the proposed monitoring work. Start by locating the middleware and any existing monitoring or configuration paths, then identify the project's test command. Done means monitoring can be configured and works with sensible defaults, with the relevant tests passing.
