Monitoring is always a good idea when deploying your application into production. Engine Yard Cloud automatically monitors your environment and adds alerts to the dashboard when abnormal resource usage occurs. You will also be notified by email if you have added a notification email address to your environment.
Important! Email notifications are disabled by default until you add a notification email address to each of your environments.
The resources that Engine Yard Cloud monitors on a per server basis include: CPU usage, IO-Wait, Swap Used, and Disk Usage.
