Observability Audit & Recommendation Summary

Current Observability Posture

• Prometheus Metrics Endpoint: exposes Prometheus metrics on an opt-in loopback listener (). Exposes core metrics such as , , , , , and .
• Structured Logging: Utilizes Rust and with for configurable log levels via .
• CI Observability Validation: Includes check-observability-pack: note: spindle_server is exported and not on the dashboard
  check-observability-pack: 7 alerts and 12 panels name 11 metrics, all exported and documented to validate dashboard JSON and Prometheus alert rule consistency against registered metrics.
• Data Flow & Exporter Policy: Zero external exporter or remote telemetry endpoint is configured. Operates under strict local-only network boundaries.

Recommendations

1. Maintain local-only telemetry boundary until an operator-confirmed backend target is configured.
2. Standardize OpenTelemetry SDK integration roadmap for distributed tracing when remote collection is requested.
3. Preserve telemetry validation script execution in CI workflows.
