Your Streamlit App Works. But Where Do the Logs Go When Production Breaks?

A Streamlit app can be up and running in minutes.

But when something breaks in production, the first question is usually:

“Where are the logs?”

If your Streamlit application is running on EC2 or Kubernetes, relying only on local logs can make debugging harder.

One practical setup is:

Streamlit → Python Logging → Watchtower → CloudWatch Logs

With boto3 and watchtower, application logs can be sent to CloudWatch, giving you one place to search and investigate production issues.

In this walkthrough, I cover the setup step by step, including log configuration and CloudWatch integration.
