Amazon CloudWatch now offers 30 days of alarm history

Amazon CloudWatch extended the duration during which customers can access their alarm history. Now, customers can view the history of their alarm state changes for up to 30 days prior.

Previously, CloudWatch provided 2 weeks of alarm history. Customers rely on alarm history to review previous triggering events, alarming trends, and noisiness. This extended history makes it easier to observe past behavior and review incidents over a longer period of time.
