Add configuration options for monitoring

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

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

**Priority**: Low/Medium

Start by locating the handlers and tracing how their configuration is currently loaded. Clarify which monitoring signals and configuration options are required, then define sensible defaults and a way to verify them. The issue is complete when handlers expose the agreed monitoring configuration and its behavior is covered by appropriate checks.
