Logging and AWS Beanstalk

After creating an ASP.NET Beanstalk application, you might be wondering, “Where are my logs?”

Without configuring CloudWatch, my logs do show within the Beanstalk UI. Note: The below image assumes no CloudWatch.

After clicking Logs, you need to click Request Logs and then select how much you want to see. I usually select Last 100 Lines.

Then I can just download the logs and look through the messages.

The “Received Request” message is a custom log I put into my code.

Making CloudWatch work with Beanstalk (abbreviates to BS which isn’t good 😊) is pretty straightforward too. No code change is required.

Click Edit in the Software section.

Enable instance log streaming to CloudWatch.
