New Check: Low Utilization Amazon EC2 Instances

[brittandeyoung]

Summary

Checks the Amazon Elastic Compute Cloud (Amazon EC2) instances that were running at any time during the last 14 days. This check alerts you if the daily CPU utilization was 10% or less and network I/O was 5 MB or less for at least 4 days.

Motivation

Running instances generate hourly usage charges. Although some scenarios can result in low utilization by design, you can often lower your costs by managing the number and size of your instances.
