Amazon CloudWatch monitors your Amazon Web Services (Amazon Web Services) resources and the
applications you run on Amazon Web Services in real time. You can use CloudWatch to collect and track
metrics, which are the variables you want to measure for your resources and
applications.
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.
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.
