Amazon CloudWatch


Amazon CloudWatch is a web service that provides monitoring for AWS cloud resources, starting with Amazon EC2. It provides customers with visibility into resource utilization, operational performance, and overall demand patterns—including metrics such as CPU utilization, disk reads and writes, and network traffic.

To use Amazon CloudWatch, simply select the Amazon EC2 instances that you’d like to monitor; within minutes, Amazon CloudWatch will begin aggregating and storing monitoring data that can be accessed using the AWS Management Console, web service APIs or Command Line Tools.
