• Amazon ElastiCache
  An Amazon ElastiCache instance is deemed to be highly utilized if the average daily CPU usage is more than 90% for the last seven days.

Site24x7 monitors for all the cases mentioned above and provides suggests for increasing efficiency and performance by identifying and stopping highly utilized instances using the Guidance Report. Instance Type recommendations show the Current Instance Type and recommend the Suggested Instance Type that you can upgrade to for better performance and efficiency.
