JSON Logging for Sanic in python
JSON Logging for Sanic
The other day I was running some containers on Amazon’s ECS and logging to cloudwatch. I then learnt cloudwatch parses JSON logs so obviously I then wanted Sanic to log out JSON.
Ideally this’ll be useful to people but if it isn’t, raise an issue and we’ll make it better 🙂
To install:
pip install sanic-json-logging
Look at examples/simple.py for a full working example, but this will essentially get you going
import sanic
from sanic_json_logging import setup_json_logging
app = sanic.Sanic(name="somename")
setup_json_logging(app)
setup_json_logging does the following:
- changes the default log formatters to JSON ones
- also filters out no Keepalive warnings
- unless told otherwise, will change the asyncio task factory, to implement some rudimentary task-local storage.
- installs pre and post request middleware. Pre-request middleware to time tasks and generate a uuid4 request id. Post-request middleware
