Logging: it's hard to tell if the application is working

Problem

The application output only it's staring (with a clear text password) but nothing after

[2024-01-22 16:14:38 +0000] [1] [INFO] Starting gunicorn 20.1.0

MONGO_URI =  mongodb://laboite:************@mongo-laboite.laboite:27017/laboite?replicaSet=rs0
MONGO_LIMIT =  10

Proposal

The application should logs when a query is made with meaning full RGPD compatible informations.
