Logging and monitoring in Elastic Beanstalk
Monitoring is important for maintaining the reliability, availability, and performance of Amazon Elastic Beanstalk and your Amazon solutions. You should collect monitoring data from all of the parts of your Amazon solution so that you can more easily debug a multipoint failure if one occurs. Amazon provides several tools for monitoring your Elastic Beanstalk resources and responding to potential incidents.
For more information about monitoring, see Monitoring an environment.
For other Elastic Beanstalk security topics, see Amazon Elastic Beanstalk security.
Enhanced health reporting
Enhanced health reporting is a feature that you can enable on your environment to allow Elastic Beanstalk to gather additional information about resources in your environment. Elastic Beanstalk analyzes the information to provide a better picture of overall environment health and help identify issues that can cause your application to become unavailable. For more information, see Enhanced health reporting and monitoring.
Amazon EC2 instance logs
The Amazon EC2 instances in your Elastic 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, Elastic Beanstalk platform scripts, and Amazon CloudFormation are stored locally on individual instances. You can easily retrieve them by using the environment management console or the EB CLI. You can also configure your environment to stream logs to Amazon CloudWatch Logs in real time. For more information, see Viewing logs from Amazon EC2 instances in your Elastic Beanstalk environment.
Environment notifications
You can configure your Elastic Beanstalk environment to use Amazon Simple Notification Service (Amazon SNS) to notify you of important events that affect your application. Specify an email address during or after environment creation to receive emails from Amazon when an error occurs, or when your environment's health changes. For more information, see Elastic Beanstalk environment notifications with Amazon SNS.
Amazon CloudWatch alarms
Using CloudWatch alarms, you watch a single metric over a time period that you specify. If the metric exceeds a given threshold, a notification is sent to an Amazon SNS topic or Amazon Auto Scaling policy. CloudWatch alarms don't invoke actions because they are in a particular state. Instead, alarms invoke actions when the state changed and was maintained for a specified number of periods. For more information, see Using Elastic Beanstalk with Amazon CloudWatch.
Amazon CloudTrail logs
CloudTrail provides a record of actions taken by a user, role, or an Amazon service in Elastic Beanstalk. Using the information collected by CloudTrail, you can determine the request that was made to Elastic Beanstalk, the IP address from which the request was made, who made the request, when it was made, and additional details. For more information, see Logging Elastic Beanstalk API calls with Amazon CloudTrail.
Amazon X-Ray debugging
X-Ray is an Amazon service that gathers data about the requests that your application serves, and uses it to construct a service map that you can use to identify issues with your application and opportunities for optimization. You can use the Amazon Elastic Beanstalk console or a configuration file to run the X-Ray daemon on the instances in your environment. For more information, see Configuring Amazon X-Ray debugging.
