Monitoring the web application environment


Once a web application is successfully deployed, it is very important to monitor it's performance. Monitoring helps to find if there is any infrastructure bottleneck, performance issue or underutilization of resources. The Elastic Beanstalk web console gives a high-level overview in terms of monitoring figures and graphs as shown in the following screenshot:

Elastic Beanstalk also offers various other methods to monitor a deployed web application, such as basic health reporting, enhanced health reporting and monitoring, managing alarms, the Elastic Beanstalk environment's event stream, listing and connecting to server instances, and viewing logs from the Elastic Beanstalk environment's EC2 instances. A detailed understanding of the various monitoring methods can be obtained from https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/environments-health.html.
