Observability suite (v2.1.0) #196

Goal

Implement advanced observability suite with performance tracing, anomaly detection, and enhanced alerting for v2.1.0.

Requirements

• Performance tracing across request chains (gateway → provider → response)
• Automated anomaly detection for latency, error rates, cost deviations
• Enhanced alerting with smart thresholds and notification channels
• GPU/utilization metrics dashboard for local workers
• Request flow visualization for debugging and optimization

Context

From v2.1.0 planning in FAIGATE-ROADMAP.md:

• Observability suite is a core theme
• Builds on basic metrics and logging in v2.0.0
• Provides operators with deep insights into gateway performance and health

Tasks

• Design observability architecture and data model
• Implement distributed tracing across request chains
• Develop anomaly detection algorithms
• Build enhanced alerting system
• Create GPU/utilization metrics collection
• Dashboard integration for observability data
• API for observability queries and exports
• Documentation and operational guides

Notes

• Complements existing dashboard and CLI monitoring
• Enables proactive issue detection and performance optimization
• Maintains gateway-first architecture with enterprise-grade observability
