python - ROS 记录器禁用 Python 记录器

Question

我在使用 Python 记录器和 rospy 记录器时遇到问题。一开始，一旦 ROS 节点被初始化，Python 记录器就停止记录。我试图通过向记录器添加流处理程序来解决这个问题。现在它只记录 ROS 节点是否初始化。

我在 ROS git 中阅读了有关 rospy 和 python 日志记录冲突的信息。但是似乎没有很好的解决方案来专门使用 python 记录器并且独立于我的代码的 ROS 记录器。

一些模块初始化记录器:

    path = "/some_directory/"
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    logger = logging.getLogger('logger_name')

    # logging file handler for basic log infos
    file_handler_info = logging.FileHandler('{}log.log'.format(path))
    file_handler_info.setFormatter(formatter)
    file_handler_info.setLevel(logging.INFO)
    logger.addHandler(file_handler_info)

    # logging file handler for critical warnings
    file_handler_critical = logging.FileHandler('{}critical.log'.format(path))
    file_handler_critical.setFormatter(formatter)
    file_handler_critical.setLevel(logging.WARNING)
    logger.addHandler(file_handler_critical)

    # logging stream handler for console output
    stream_handler = logging.StreamHandler()
    stream_handler.setFormatter(formatter)
    stream_handler.setLevel(logging.DEBUG)
    logger.addHandler(stream_handler)

启动 ROS 节点的其他一些模块

logger.info("This message will not be displayed")
rospy.init_node('node_name', anonymous=True)
logger.info("This message will be displayed")

rospy 提供 overriding the default logging configuration :

By default, rospy and other ROS python libraries use $ROS_ROOT/../../etc/ros/python_logging.conf. This file is the standard fileConfig format used by the Python logging module (see https://docs.python.org/library/logging.config.html#configuration-file-format).

You can override the location of this configuration file by setting the ROS_PYTHON_LOG_CONFIG_FILE environment variable.

自定义或创建您自己版本的 python_logging.conf放在 /opt/ros/YOUR_ROS_DISTRO/etc/ros/默认情况下。
也许加上 streamHandler就已经足够了到根记录器:

[logger_root]
level=DEBUG
handlers=fileHandler,streamHandler
