JsonLogging format

Hi folks, could be possible a Json format logger? i’m using elasticsearch to log data, and json is very intuitive there’s a logger but i don’t know how to use it with uvicorn:

from pythonjsonlogger.jsonlogger import JsonFormatter
JsonFormatter("(asctime) (levelname) (name) (module) (funcName) (lineno) (message)")

This is something that I do in all of my projects. Currently, I am running gunicorn with the uvicorn worker and passing a custom logfile like so:

$ gunicorn example:app -w 2 -k uvicorn.workers.UvicornWorker --log-config logging_config.conf

The logging_config.conf looks like this:

[loggers]
keys=root, uvicorn, gunicorn

[handlers]
keys=access_handler

[formatters]
keys=json

[logger_root]
level=INFO
handlers=access_handler
propagate=1

[logger_gunicorn]
level=INFO
handlers=access_handler
propagate=0
qualname=gunicorn

[logger_uvicorn]
level=INFO
handlers=access_handler
propagate=0
qualname=uvicorn

[handler_access_handler]
class=logging.StreamHandler
formatter=json
args=()

[formatter_json]
class=pythonjsonlogger.jsonlogger.JsonFormatter

Note that for high throughput, the uvicorn docs mention turning off access logging, which I have not done here.

Hello all, since it looks like this is mostly a logging configuration question and that some solutions were provided above, I’m going to close this off for housekeeping purposes. Thanks!
