CloudWatch: Alarms, Dashboards, and SLOs for the API
With logs, traces, and metrics in place, the next step is knowing automatically when the system has a problem. Define SLOs for the API, build CloudWatch alarms that fire when errors or throttles cross a threshold, gather metrics into a dashboard, and use Logs Insights to compute indicators from structured logs. Push a real alarm into ALARM state by causing a throttle.
