python - Disable logging in gunicorn for a specific request / URL / endpoint

Question

Recently, there was the question of how to disable logging in Python Flask for a specific endpoint (Skip Flask logging for one endpoint?).

This makes sense for example for /healthcheck which you don't want to clutter your logs.

I solved this for Flask, but when running Flask using Gunicorn my solution doesn't work anymore.

How do I achieve this using Gunicorn? I want regular logging behavior, but not have any logs for the /healthcheck endpoint.

The pre_request hook wasn't working for me. I used the answer from https://stackoverflow.com/a/52455408/2339067 to create the following gunicorn.conf.py file:

import logging
from gunicorn import glogging


class CustomGunicornLogger(glogging.Logger):

    def setup(self, cfg):
        super().setup(cfg)

        # Add filters to Gunicorn logger
        logger = logging.getLogger("gunicorn.access")
        logger.addFilter(HealthCheckFilter())

class HealthCheckFilter(logging.Filter):
    def filter(self, record):
        return 'GET /healthcheck' not in record.getMessage()

accesslog = '-'
logger_class = CustomGunicornLogger
