How to make imported modules respect logging formats?

[jseiser]

Im basically using the logging configuration from the README. Its working fine, except for logs/exceptions that are bubbling up from a module i am using https://github.com/jasonrbriggs/stomp.py

These just log as plain text to the console.

I have a logger.py

from pythonjsonlogger import jsonlogger
import logging
from datetime import datetime

class CustomJsonFormatter(jsonlogger.JsonFormatter):
    def add_fields(self, log_record, record, message_dict):
        super(CustomJsonFormatter, self).add_fields(log_record, record, message_dict)
        if not log_record.get("timestamp"):
            now = datetime.utcnow().strftime("%Y-%m-%dT%H:%M:%S.%fZ")
            log_record["timestamp"] = now
        if log_record.get("level"):
            log_record["level"] = log_record["level"].upper()
        else:
            log_record["level"] = record.levelname

logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)
logHandler = logging.StreamHandler()
fileHandler = logging.FileHandler("messagebus.log")
formatter = CustomJsonFormatter("%(timestamp)s %(level)s %(name)s %(message)s")
logHandler.setFormatter(formatter)
fileHandler.setFormatter(formatter)
logger.addHandler(logHandler)
logger.addHandler(fileHandler)

then i import it in my app by doing

import stomp
from logger import logger

Logs I create via logger.info etc all show as JSON, logs coming from stomp, just come as plain text.

Any help would be great.

Thanks,

this line was my problem logger = logging.getLogger(__name__)
