High-Resolution Custom Metrics and Alarms enables you to monitor custom applications and infrastructure in near real-time, even per-second resolution, with CloudWatch. In addition, you can also alert sooner with High-Resolution Alarms, as frequently as 10-second periods.
High-Resolution Alarms allow you to react and take actions faster, and support the same actions available today with standard 1-minute alarms. You can add these high-resolution metrics and alarms widgets to your Dashboards giving you easy observability of critical components.
