Using Amazon CloudWatch with HealthImaging
You can monitor AWS HealthImaging using CloudWatch, which collects raw data and processes it into readable, near real-time metrics. These statistics are kept for 15 months, so you can use that historical information and gain a better perspective on how your web application or service is performing. You can also set alarms that watch for certain thresholds, and send notifications or take actions when those thresholds are met. For more information, see the Amazon CloudWatch User Guide.

Creating an alarm using CloudWatch
A CloudWatch alarm watches a single metric over a specified time period, and performs one or more actions: sending a notification to an Amazon Simple Notification Service (Amazon SNS) topic or Auto Scaling policy. The action or actions are based on the value of the metric relative to a given threshold over a number of time periods that you specify. CloudWatch can also send you an Amazon SNS message when the alarm changes state.
CloudWatch alarms invoke actions only when the state changes and has persisted for the period you specify. For more information, see Using CloudWatch alarms.
