Rust Metrics for Services: Prometheus Exporters, Histograms, Labels, and Alert Signals

A practical two-hour session on Rust Metrics for Services, focused on Prometheus Exporters, Histograms, Labels, and Alert Signals. Rust is used as the implementation context while the core lesson stays on software engineering fundamentals, reliability, testing, and operational clarity.

Audience: entry-level and intermediate developers who want a practical engineering session, not a language tour.

Outcomes:

• Explain the practical boundaries of Rust Metrics for Services
• Apply Prometheus Exporters in a small working example
• Apply Histograms in a small working example
• Apply Labels in a small working example

Format: two hours with a short framing walkthrough, a concrete example, discussion of tradeoffs, and a closing checklist for practice.
