Best Practices

Log Management

Use structured logging with proper levels
Implement log rotation and retention policies
Set up log aggregation for distributed systems
Monitor log patterns for anomalies

Metrics Collection

Collect metrics at appropriate intervals
Use consistent metric naming conventions
Implement metric aggregation and rollup
Set up alerting on critical metrics

Healthcheck Design

Design healthchecks to test critical functionality
Use appropriate timeouts and intervals
Implement circuit breaker patterns
Monitor healthcheck failures and trends

Performance Optimization

Use appropriate sampling rates for metrics
Implement caching for frequent queries
Optimize database queries and indexes
Monitor API performance and resource usage

For detailed schema definitions, refer to the OpenAPI specification published alongside the backend service.
