# Elastic Cloud Compute (EC2)

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.

## aws.ec2.CPUCreditBalance

The CPU credit balance of an instance, based on what has accrued since it started. For more information, refer to the Elastic Compute Cloud metric definition table.

## aws.ec2.CPUUtilization

The percentage of allocated EC2 compute units currently in use on the instance. For more information, refer to the Elastic Compute Cloud metric definition documentation.

This metric identifies the processing power required to run an application upon a selected instance.

## aws.ec2.DiskReadBytes

The total bytes read from all ephemeral disks available to the instance. This metric is used to determine the volume of the data the application reads from the disk and can be used to determine the speed of the application.

The number reported is the number of bytes received during a specified period. For a basic (five-minute) monitoring, divide this number by 300 to find Bytes/second. For a detailed (one-minute) monitoring, divide it by 60.

For more information, refer to the Elastic Compute Cloud metric definition documentation.

## aws.ec2.DiskWriteBytes

It is the total bytes written to all ephemeral disks available to the instance. This metric is used to determine the volume of the data the application writes to the disk and can be used to determine the speed of the application.

The number reported is the number of bytes received during a specified period. For a basic (five-minute) monitoring, divide this number by 300 to find Bytes/second. For a detailed (one-minute) monitoring, divide it by 60.
