Streaming Logs to Amazon CloudWatch

You can configure your AWS Elastic Beanstalk environment to stream Amazon CloudWatch logs from the Amazon EC2 instances that run your application.

When you configure CloudWatch logs, Elastic Beanstalk creates CloudWatch log groups for proxy and deployment logs on the Amazon EC2 instances and transfers these log files to CloudWatch logs in real time.

Configuring Log Streaming

You can enable log streaming in the Elastic Beanstalk console.

To configure log streaming in the Elastic Beanstalk console

  1. Open the Elastic Beanstalk console.

  2. Navigate to the management page for your environment.

  3. Choose Configuration.

  4. In the Software Configuration section, choose the settings icon ( Edit ).

  5. Under CloudWatch logs, configure the following settings.

    • Log streaming – Check to enable log streaming.

    • Retention – The number of days to retain logs in CloudWatch

    • Lifecycle – Set to Delete logs upon termination to delete logs from CloudWatch immediately if the environment is terminated, instead of waiting for them to expire.

  6. Choose Apply.

After you enable log streaming, you can return to the configuration page to find a link to log group in the CloudWatch console.
