Configure non-root logger?

[spyoungtech]

It seems that this library sets configuration on the root logger. Is there a way to set formatter on a non-root logger?

For example, we have loggers that do not propagate to the root logger that we'd like to have json logging for.

logger = logging.getLogger(__name__)
handler = logging.StreamHandler(sys.stderr)
# handler.setFormatter(...)  # how to set json logging format here?
logger.addHandler(handler)
logger.propagate = False
...

Reason is we only want one particular log to have this format, while leaving other unchanged.

you can explicitly add handler to that specific logger, something like that:

handler = logging.handlers.RotatingFileHandler(filename='log_req.log', maxBytes=5000000, backupCount=10)
handler.setFormatter(json_logging.JSONLogFormatter())
logger.addHandler(handler)
