📊 Monitoring

Health Checks

The application provides comprehensive health checks:

Database connectivity
Redis connectivity

Metrics

Prometheus metrics are exposed at /metrics:

Request duration and count
Database connection pool stats
Queue processing metrics
External API call metrics
Circuit breaker stats

Logging

Structured JSON logging with configurable levels:

{
  "timestamp": "2024-01-01T12:00:00Z",
  "level": "info",
  "message": "Deployment created",
  "deployment_id": "123",
  "project": "user-service",
  "environment": "production"
}

🔄 Queue Processing

Background Jobs

Jira Ticket Creation: Async processing with retry logic
Slack Notifications: Batched message sending
SLA Metric Calculation: Periodic metric updates
Data Cleanup: Scheduled cleanup of old records

Queue Configuration

# Redis Queue Settings
queues:
  jira:
    workers: 5
    retry_attempts: 3
    retry_delay: 30s

🚀 Deployment

Production Deployment

Scaling Guidelines

Horizontal Scaling:

Each instance is stateless
Use load balancer for traffic distribution
Scale based on CPU/memory metrics

Database Scaling:

Read replicas for read-heavy workloads
Connection pooling optimization
Query optimization and indexing

Redis Scaling:

Redis Cluster for high availability
Separate queues for different job types
Monitor queue length and processing time

🐛 Troubleshooting

Common Issues

High Memory Usage

# Check goroutine leaks
curl http://localhost:8080/debug/pprof/goroutine

# Monitor garbage collection
GODEBUG=gctrace=1 ./dep-tracker-backend

Database Connection Issues

# Check connection pool stats
curl http://localhost:8080/metrics | grep db_connections

# Validate database connectivity
make db-ping

Queue Processing Delays

# Monitor queue lengths
redis-cli llen jira_queue
redis-cli llen slack_queue

# Check worker status
curl http://localhost:8080/health

Debug Mode

# Enable debug logging
export LOG_LEVEL=debug
export GIN_MODE=debug

# Enable pprof endpoint
export ENABLE_PPROF=true
