[KA-CHOW] fix(evaluator): Service evaluator is in critical health (score: 45)

🔧 KA-CHOW Self-Healing Patch

Service: evaluator
Issue type: Service evaluator is in critical health (score: 45)

What changed

The code was updated to include a retry mechanism with exponential backoff for handling transient errors during the evaluation of the service health. A try/except block was added to catch exceptions and log them, ensuring that errors are not silently ignored. The retry mechanism attempts the operation up to three times, doubling the delay between each attempt, which helps in dealing with temporary issues without overwhelming the service.

Patch

def evaluate_service_health(service):
    import time
    import logging
    
    max_retries = 3
    retry_delay = 1  # initial delay in seconds
    
    for attempt in range(max_retries):
        try:
            # Simulate service evaluation logic
            health_score = service.get_health_score()
            if health_score < 50:
                raise ValueError("Critical health score")
            return health_score
        except Exception as e:
            logging.error(f"Attempt {attempt + 1}: Error evaluating service health: {e}")
            if attempt < max_retries - 1:
                time.sleep(retry_delay)
                retry_delay *= 2  # Exponential backoff
            else:
                raise
