Phase 6: Observability & Production Readiness

Overview

Complete observability setup with OpenTelemetry, integrate error reporting with Sentry, enhance logging with correlation IDs, and add rate limiting.

Tasks

6.1 OpenTelemetry Completion

• 6.1.1 - Complete OpenTelemetry Setup
• 6.1.2 - Create Custom Spans
• 6.1.3 - Add Trace Context Propagation

6.2 Error Reporting (Sentry)

• 6.2.1 - Install Sentry
• 6.2.2 - Integrate with Error Bus
• 6.2.3 - Add Sentry Middleware
• 6.2.4 - Configure Sentry DSN

6.3 Enhanced Logging

• 6.3.1 - Add Request Correlation
• 6.3.2 - Add Structured Fields
• 6.3.3 - Create Log Aggregation Config

6.4 Rate Limiting

• 6.4.1 - Create Rate Limiter Interface
• 6.4.2 - Implement Redis Rate Limiter
• 6.4.3 - Add Rate Limit Middleware

6.5 Production Configuration

• 6.5.1 - Create Production Config Template
• 6.5.2 - Add Environment-Specific Settings

Deliverables Checklist

• OpenTelemetry fully integrated with custom spans
• Sentry error reporting working
• Enhanced logging with correlation IDs
• Rate limiting middleware implemented
• Production configuration templates ready
• All observability data flowing to external systems

Acceptance Criteria

• Traces are exported to OTLP endpoint
• Errors are reported to Sentry
• Logs include correlation IDs
• Rate limiting prevents abuse
• Production configs are validated
• All metrics are exposed via Prometheus
