在Heroku上生成的日志对于调试和故障排除非常重要,但有时可能会生成大量不必要的日志,导致日志文件快速增长,占用存储空间并增加成本。以下是一些解决方法来避免在Heroku上生成不必要的日志。
import logging
# Set the logging level
logging.basicConfig(level=logging.WARNING)
# Log an error
logging.error("This is an error message")
# Log a warning
logging.warning("This is a warning message")
# Log an info message (will not be logged with the above basicConfig)
logging.info("This is an info message")
# Log a debug message (will not be logged with the above basicConfig)
logging.debug("This is a debug message")
import logging
# Set the logging level
logging.basicConfig(level=logging.INFO)
# Log a message only if a condition is met
condition = True
if condition:
logging.info("This is a log message")
import logging
# Create a logger with a specific name
logger = logging.getLogger('my_module')
# Set the logging level
logger.setLevel(logging.INFO)
# Log a message
logger.info("This is a log message from my_module")
import logging
# Create a logger
logger = logging.getLogger()
logger.setLevel(logging.INFO)
# Create a filter to only log messages containing 'important'
filter = logging.Filter('important')
# Add the filter to the logger
logger.addFilter(filter)
# Log a message containing 'important'
logger.info("This is an important log message")
# Log a message without 'important'
logger.info("This is not an important log message")
这些是一些常见的方法来避免在Heroku上生成不必要的日志。根据您的具体需求和应用程序的特点,您可以选择适合您的解决方案。
