Implement Advanced CloudWatch Monitoring for a Web Server

CloudWatch Logs centralizes the logs from all of your systems, applications, and AWS services that you use, in a single, highly scalable service. In this lab, you will configure an EC2 instance to stream its Apache web server error logs to CloudWatch Logs. You will configure the agent and then log in to the CloudWatch Logs console to make sure the logs are streamed correctly. By the end of this lab, you will understand how to install the CloudWatch Logs agent and configure it to stream a log to the service.
