Error messages can appear as events on the Beanstalk environment management page in the console, in logs, or on the health page. Try the following:
- Review recent environment events. Messages from Elastic Beanstalk about deployment, load, and configuration issues often appear here and may highlight what the issue is.
- Pull logs to view recent log file entries. Web server logs contain information about incoming requests and errors. The instances in your Beanstalk environment generate logs that you can view to troubleshoot issues with your application or configuration files. Logs created by the web server, application server, Beanstalk platform scripts, and CloudFormation are stored locally on individual instances. You can easily retrieve them by using the Beanstalk management console or the EB CLI.
- Connect to an instance and check system resources. It could be the application failed with an error, disk space is exhausted, or if you are using burstable compute resources (t2) you may have exhausted cpu credits.
Consider deploying a new environment. If the environment appears healthy, perform a CNAME swap to route traffic to the new environment and continue to debug the earlier one.
