Health Check System

This module provides comprehensive health checking functionality for DMSC modules and services. It supports both active health checks (proactive monitoring) and passive health indicators (reactive status reporting).

Key Components

• HealthStatus: Enum representing the health state of a component
• HealthCheck: Trait for implementing custom health checks
• HealthChecker: Service for managing and executing health checks
• HealthReport: Comprehensive health status report

Design Principles

1. Non-Intrusive: Health checks can be added without modifying existing code
2. Configurable: Check intervals, timeouts, and thresholds are configurable
3. Comprehensive: Supports multiple health indicators and aggregation
4. Performance-Aware: Minimal impact on system performance
5. Extensible: Easy to add new health check types
