Amazon CloudWatch now lets customers evaluate metrics data for an extended duration of up to 7 days, a 7x increase from the previous limit of 24 hours.
This enhancement empowers customers to monitor the health of longer-running or infrequent processes, such as daily data loading jobs or day-over-day performance trends, offering deeper insights into their resources and applications. Customers now have the flexibility to leverage CloudWatch alarms for use cases like near-real-time metric tracking as well as for monitoring patterns that span multiple days.
Amazon CloudWatch alarming on multi-day data is now available in all AWS Regions including the AWS GovCloud (US) Regions .
To alarm on multiple days of data, create or update an alarm using the CloudWatch console or Command Line Interface (CLI) , specify a period of at least 3,600 (1 hour) and the number of datapoints that you want to compare against the threshold.
