*
* Amazon EC2 sends metrics to CloudWatch that describe your Auto Scaling instances. These metrics
* are available for any EC2 instance, not just those in an Auto Scaling group. For more
* information, see Instance Metrics in the Amazon EC2 User Guide for Linux Instances.
*
* Auto Scaling groups can send metrics to CloudWatch that describe the group itself. You must
* enable these metrics.
*
* To filter the metrics for your Auto Scaling group by group name, use the "AutoScalingGroupName"
