Add unit tests for middleware

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

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

**Priority**: Low/Medium

Start by locating the middleware and controller code referenced in the issue, then inspect how monitoring is currently handled. Add unit coverage for the requested configurable monitoring behavior and sensible defaults, and run the relevant test command to confirm the middleware cases pass.
