You can use CloudWatch to collect and track metrics, which are the variables you want to measure for your resources and applications. CloudWatch has the following limits: You get 10 CloudWatch metrics, 10 alarms, 1,000,000 API requests, and 1,000 Amazon SNS email notifications per customer per month for free.
