Modify the Period for a Graph
CloudWatch enables you to view your data at different granularities. You can view your data using Period of 1 minute, giving you a very detailed view. This is very useful when troubleshooting, when viewing narrow bands of time (e.g. 1 hour), and when performing other activities that require the most precise graphing of time periods. You can also view your data using Period of 1 hour, giving you a less detailed view. This is very useful when viewing wider bands of time (e.g. 3 days), and allows you to see trends over time. For more information, see Periods.
