Trying to understand logging in Python with structlog...

test_script.py

# Two main things I can't figure out:
# 1. How do I get the name of each function to prefix its log entry?
#    e.g., INFO:testmodule:outsideFun:{msg} instead of just INFO:testmodule:{msg}
# 2. How do I get bound values to persist through subsequent functions?
#    e.g., user:matt.parker and outsideArg:foo should appear in both 
#   outsideFun and insideFun log messages

import logging
import structlog
import testmodule


# Set up the log  
logging.basicConfig(level = logging.DEBUG)

structlog.configure(
    processors = [structlog.stdlib.filter_by_level,
                  structlog.processors.format_exc_info,
                  structlog.processors.TimeStamper(fmt = 'iso'),
                  structlog.processors.JSONRenderer()],
    context_class = dict,
    logger_factory = structlog.stdlib.LoggerFactory(),
    wrapper_class = structlog.stdlib.BoundLogger,
    cache_logger_on_first_use = True
    )
    
logger = structlog.get_logger()



# Bind a key-value that should appear in all output
logger = logger.bind(user = "matt.parker")

    
# Run the function
testmodule.outsideFun()

testmodule.py

import structlog


module_logger = structlog.get_logger()


def insideFun(insideArg = "bar"):
    
    logger = structlog.get_logger()
    logger = logger.bind(insideArg = insideArg)
    logger.info("Inside function has begun.")
    
    print insideArg
    
    logger.info("Inside function complete.")




def outsideFun(outsideArg = "foo"):
    
    logger = structlog.get_logger()
    logger = logger.bind(outsideArg = outsideArg)
    logger.info("Starting the outside function...")
    
    insideFun()    
    
    logger.info("Outside function complete.")
