Question

A SysOps administrator manages a workload deployed across three AWS Regions (us-east-1, eu-west-1, and ap-southeast-2). Leadership wants a single CloudWatch dashboard that displays EC2 CPU utilization and Application Load Balancer request counts from all three Regions on the same set of widgets, so operators can monitor global health from one screen. What is the MOST operationally efficient way to achieve this?

Accepted Answer

Build a single cross-Region CloudWatch dashboard and add metric widgets that reference metrics from each Region within the same dashboard.

Answer

Create a separate CloudWatch dashboard in each Region and switch the console Region manually to view each one.

Answer

Configure metric streams to push all Regional metrics into a single Region's custom namespace, then build a dashboard on the aggregated custom metrics.

Answer

Enable CloudWatch cross-account observability and view each Region's metrics through the monitoring account console.
