    A class for managing and monitoring errors in a system with limited error recovery capabilities.
    
    Attributes:
        max_retries (int): Maximum number of retries before giving up on an operation.
        error_threshold (float): Percentage threshold at which the system will stop retrying operations.
        failed_operations (Dict[str, int]): A dictionary to keep track of failed operations and their counts.
        
    Methods:
        __init__: Initializes ErrorMonitor with given parameters.
        monitor_error: Monitors errors in a system operation and decides whether to retry based on thresholds.
        log_failure: Logs the failure of an operation.
