From Wikipedia:

Amazon CloudWatch is a web service that provides real-time monitoring to Amazon's EC2 customers on their resource utilisation such as CPU, disk and network. CloudWatch does not provide any memory, disk space, or load average metrics without running additional software on the instance. Amazon provides example scripts for Linux instances. The data is aggregated and provided through AWS management console. It can also be accessed through command line tools and Web API's if the customer desires to monitor their EC2 resources through their enterprise monitoring software.

In addition to various built-in Amazon CloudWatch Metrics; developers can publish custom metrics to report on virtually any continuous dataset generated by the application. Several commercial products are capable of ingesting CloudWatch data and displaying it alongside data about deployment, user behaviour, marketing campaigns and business performance indicators.
