You can use CloudWatch to collect and track metrics, which are the variables you * want to measure for your resources and applications. * </p> * <p> * CloudWatch alarms send notifications or automatically change the resources you are monitoring based on rules that you * define. For example, you can monitor the CPU usage and disk reads and writes of your Amazon EC2 instances. 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 Amazon Web Services, 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;
