How to change the log level of Azure SDK for Python

Introduction

I wanted to persist the data of Azure App Service with CosmosDB, so I added the ʻazure-cosmos` library with pip and implemented the connection process.

requirements.txt

azure-cosmos==4.0.0

After implementation, when debugging, I noticed a lot of logs about the Azure SDK package ʻazure.core.pipeline.policies.http_logging_policy`.

In this article, I will show you how to suppress the log output by changing the log level of the above logger.

Log output example

In my environment, the following log was output.

Workaround

ʻAzure.core.pipeline.policies.http_logging_policy` You can suppress unnecessary logs by setting the log level in the logger.

application.py

logging.getLogger('azure.core.pipeline.policies.http_logging_policy').setLevel('WARNING')

In this example, logs of log level WARNING or higher are output. If you want to set other logging levels, see logging — Logging facility for Python — Python 3.8.3 documentation (https://docs.python.org/3.8/library/logging.html#levels). ..
