@Marvin is the JsonFormatter still supported as a logging formatter to be used in logging.yaml ?

The

JsonFormatter

directly is not explicitly mentioned in the Prefect documentation for versions 2.x or 3.x. However, Prefect does provide ways to customize logging configurations using a

logging.yml

file, and you can employ any formatter supported by Python's standard logging module, including JSON formatters. Here are the steps you can take to configure a

JsonFormatter

in `logging.yml`: 1. Ensure you have a JSON formatter available, such as

python-json-logger

. 2. Create or modify your

logging.yml

file to include your JSON formatter settings. Here are useful links and references from the Prefect documentation: - Prefect 2.x Logging Guide: Prefect 2.x Logging - Prefect 3.x Logging Guide: Prefect 3.x Logging You can configure a

JsonFormatter

in the

logging.yml

like this:

yaml
version: 1
formatters:
  json:
    '()': pythonjsonlogger.jsonlogger.JsonFormatter
handlers:
  console:
    class: logging.StreamHandler
    formatter: json
loggers:
  prefect:
    level: INFO
    handlers: [console]
    propagate: no
root:
  level: WARNING
  handlers: [console]

Ensure to install

python-json-logger

with:

bash
pip install python-json-logger
