Logging

Centralized logging configuration for TAF.

This module provides logging configuration that can be imported and used throughout the project. Each module should use:

import logging
logger = logging.getLogger(__name__)

This ensures proper hierarchical logging with module-specific loggers.

Typical usage example

from agentflow.utils.logging import configure_logging configure_logging(level=logging.DEBUG)

Functions:

Name	Description
configure_logging	Configures the root logger for the TAF project.

Functions

configure_logging

configure_logging(level=logging.INFO, format_string=None, handler=None)

Configures the root logger for the TAF project.

This function sets up logging for all modules under the 'agentflow' namespace. It ensures that logs are formatted consistently and sent to the appropriate handler.

Parameters:

Name	Type	Description	Default
level	int	Logging level (e.g., logging.INFO, logging.DEBUG). Defaults to logging.INFO.	INFO
format_string	str	Custom format string for log messages. If None, uses a default format: "[%(asctime)s] %(levelname)-8s %(name)s: %(message)s".	None
handler	Handler	Custom logging handler. If None, uses StreamHandler to stdout.	None

Returns:

Type	Description
None	None

Example

configure_logging(level=logging.DEBUG) logger = logging.getLogger("agentflow.module") logger.info("This is an info message.")
