Enhance Cache Monitoring with Comprehensive Logging and Event Tracking

Description

Task

Add cache monitoring and logging

Acceptance Criteria

• Implement comprehensive cache monitoring
• Track detailed cache operation statistics
• Provide real-time event tracking
• Support flexible event listening
• Maintain type safety and robust error handling

Summary of Work

This pull request implements a robust cache monitoring system that provides detailed insights into cache performance and operations.

Key Changes

• Enhanced CacheMonitor class with comprehensive event tracking
• Added detailed logging methods for cache operations
• Implemented singleton pattern for global cache monitoring
• Provided flexible event listening and statistic tracking

Implementation Details

1. Cache Statistics Tracking

   • Track cache hits, misses, sets, and deletes
   • Maintain real-time statistics with getStats() method
   • Ability to reset statistics using resetStats()

2. Event-Driven Monitoring

   • Implemented EventEmitter for real-time cache event tracking
   • Support for listening to specific cache events:
     • hit: When a cache entry is successfully retrieved
     • miss: When a requested cache entry is not found
     • set: When a new cache entry is created
     • delete: When a cache entry is removed

3. Extensibility

   • Singleton pattern ensures consistent monitoring across the application
   • Flexible event listener registration with on() method

Testing Approach

• Verified method implementations for each cache operation
• Tested event emission and statistic tracking
• Ensured type safety and comprehensive error handling
• Validated singleton instantiation

Notes

• The implementation uses Node.js native EventEmitter
• Lightweight and performance-friendly design
• Easy integration with existing caching mechanisms

Changes Made

• Enhanced CacheMonitor class with comprehensive event tracking
• Added methods to record and track cache hits, misses, sets, and deletes
• Implemented singleton pattern for global cache monitoring
• Created flexible event listening mechanism
• Added method to retrieve and reset cache statistics

Tests

• Verify cache hit tracking works correctly
• Verify cache miss tracking works correctly
• Test event emission for different cache operations
• Validate statistics retrieval and reset functionality
• Ensure type safety of all monitoring methods
