Dimensions for EC2 Metrics

EC2 instance data can be filtered along any of the following dimensions in the table below.

DimensionSection
ImageId This dimension filters the data you request for all instances running this EC2 Amazon Machine Image (AMI).
AutoScalingGroupName This dimension filters the data you request for all instances in a specified capacity group. An AutoScalingGroup is a collection of instances defined by customers of the Auto Scaling service. This dimension is only available for EC2 metrics when the instances are in such an AutoScalingGroup.
InstanceId This dimension filters the data you request for only the identified instance. This allows a user to pinpoint an exact instance from which to monitor data.
InstanceType This dimension filters the data you request for all instances running with this specified instance type. This allows a user to categorize his data by the type of instance running. For example, a user might compare data from an m1.small instance and an m1.large instance to determine which has the better business value for his application.

Dimensions for Load Balancing Metrics

Load Balancing Service data can be aggregated along any of the following dimensions shown in the table below.

Load Balancing MetricsSection
LoadBalancerName This dimension filters the data you request for the specified LoadBalancer name. A LoadBalancer is represented by a DNS name and provides the single destination to which all requests intended for your application should be directed.
