Support monitoring configuration

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

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

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

The issue names no files, tests, or entry points. Start by locating the monitoring configuration and error-handling entry points, then clarify which data-related failures and message details are in scope. Done means the agreed monitoring support works and the relevant errors provide the specified diagnostic context.
