Alarm Recommendations
Overview
CloudWatch provides out-of-the-box alarm recommendations to help you identify key metrics to monitor based on AWS best practices. These recommendations include suggested metrics, thresholds, and pre-filled alarm settings, making it easier to set up effective monitoring for your AWS infrastructure. These alarms can be utilized within threat detection and hunting for anomalous behavior.
