Management and injection of contextual variables into log messages.

import logging
import logctx

root_logger = logging.getLogger()
console_handler = logging.StreamHandler()

formatter = jsonlogger.JsonFormatter("%(logctx)s")
context_filter = ContextInjectingLoggingFilter(output_field="logctx")

console_handler.setFormatter(formatter)
console_handler.addFilter(context_filter)

root_logger.addHandler(console_handler)
logger.setLevel(logging.DEBUG)
