Explore metric anatomy

Use the metric anatomy explorer to examine how CloudWatch metrics are structured. The explorer shows the components of a metric: namespace, metric name, dimensions, value, timestamp, and unit.

Toggle between standard and custom metrics and between standard and high resolution, then read the granularity verdict at the bottom to check whether your chosen type and resolution can hit 1-second granularity.

Question: Your team needs to monitor a payment processing Lambda function with 1-second granularity during peak hours. Which metric type and resolution should you use?
