Add rate limiting for monitoring

**Problem**
When working with components, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

Start by locating the monitoring and component error-handling entry points, then read the existing error-message paths and related tests. Clarify which errors need more detail and how monitoring should be rate-limited; done means the requested messages and limiting behavior are covered by verification.
