The checks and recommendations aren't very sophisticated, though. E.G. the Low Utilization Amazon EC2 Instances check: Checks the Amazon Elastic Compute Cloud (Amazon EC2) instances that were running at any time during the last 14 days and alerts you if the daily CPU utilization was 10% or less and network I/O was 5 MB or less on 4 or more days.
