BE-016 — Implement Protocol Health & System Monitoring API

📚 Overview

The Protocol Health & System Monitoring API provides comprehensive visibility into the operational health of the TruthBounty infrastructure.

As TruthBounty evolves into a distributed ecosystem comprising smart contracts, backend services, blockchain indexers, AI services, analytics, governance, and notification systems, operators require a centralised interface for monitoring system health, performance, availability, and operational incidents.

The Monitoring API aggregates metrics from infrastructure and application services without becoming responsible for protocol state.

The Protocol Health API will become the dependency for:

• Operations Dashboard
• Administration Portal
• DevOps Monitoring
• AI Operations Assistant
• Incident Response Platform
• Alerting Service
• Analytics Dashboard

Every operational service assumes monitoring data is accurate, timely, and reflects the current health of the platform.

---

🧠 Background

TruthBounty V2 consists of multiple independent services including:

• API Gateway
• Authentication Service
• PostgreSQL
• Redis
• Blockchain Indexer
• Smart Contract RPC connections
• Governance Service
• Analytics Service
• AI Assistant
• Notification Service
• Background Workers

Failure within any component can affect contributor experience.

A dedicated monitoring layer provides proactive visibility into failures before they impact users.

The Monitoring API should expose operational metrics but must never modify protocol behaviour.

---

🎯 Objectives

Implement a production-ready Monitoring API that:

• exposes service health
• reports infrastructure metrics
• monitors protocol services
• aggregates operational statistics
• exposes readiness and liveness endpoints
• supports observability tooling
• enables alerting integrations
• returns standardised API responses

---

🧩 Technical Scope

1. Health Endpoints

Implement:

• /health
• /ready
• /live

Return overall system status together with individual service health.

---

2. Service Health Monitoring

Monitor:

• API Gateway
• PostgreSQL
• Redis
• Blockchain Indexer
• Notification Service
• AI Assistant
• Analytics Service
• Governance Service
• Background Workers

Each service should expose independent health information.

---

3. Infrastructure Metrics

Collect:

• CPU usage
• memory usage
• disk usage
• network traffic
• process count
• container status
• uptime

Support future Kubernetes deployments.

---

4. Database Monitoring

Expose:

• active connections
• slow queries
• replication status
• storage utilisation
• query latency
• migration status

---

5. Blockchain Monitoring

Track:

• RPC availability
• latest indexed block
• indexing delay
• chain synchronisation
• failed blockchain requests
• smart contract connectivity

---

6. Queue Monitoring

Monitor:

• Redis queues
• notification queues
• background jobs
• failed jobs
• retry queues
• queue processing latency

---

7. Performance Metrics

Expose:

• API response time
• request throughput
• error rate
• cache hit ratio
• worker execution time
• websocket connections

---

8. Alert Integration

Support integration with:

• Prometheus
• Grafana
• Alertmanager
• OpenTelemetry
• Datadog
• external monitoring systems

Alert thresholds should be configurable.

---

9. Historical Metrics

Provide historical monitoring for:

• uptime
• response latency
• resource utilisation
• service availability
• indexing performance

Support configurable reporting periods.

---

10. API Standardisation

Return consistent response objects containing:

• health status
• metrics
• timestamps
• service metadata
• version information
• request identifier

Errors must follow backend API standards.

---

✅ Acceptance Criteria

• Health endpoints function correctly.
• Infrastructure metrics are available.
• Database monitoring operates correctly.
• Blockchain monitoring reports accurately.
• Queue metrics are exposed.
• Performance statistics are available.
• Monitoring integrations function correctly.
• Unit and integration tests pass.

---

🧪 Testing Requirements

Implement tests covering:

• health endpoints
• readiness checks
• liveness checks
• infrastructure monitoring
• blockchain monitoring
• queue monitoring
• metrics aggregation
• alert integrations
• concurrent requests
• performance benchmarking

---

📚 Documentation

Update:

• Backend API Documentation
• Monitoring Architecture
• OpenAPI Specification
• DevOps Guide
• Operations Runbook
• Incident Response Guide

---
