For example, you can monitor the CPU usage and disk reads and writes of your Amazon Elastic Compute * Cloud (Amazon EC2) instances and then use this data to determine whether you should launch additional instances to * handle increased load. You can also use this data to stop under-used instances to save money. * </p> * <p> * In addition to monitoring the built-in metrics that come with AWS, you can monitor your own custom metrics. With * CloudWatch, you gain system-wide visibility into resource utilization, application performance, and operational * health. * </p> */ package com.amazonaws.services.cloudwatch;
