Create a Cross-Region Dashboard
You can monitor multiple resources in different locations on a single dashboard. For example, you might want to create a dashboard showing CPU utilization for an Amazon EC2 instance located in the us-west-2 region with your billing metrics, which are located in us-east-1 region.
To create a cross-region dashboard
Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.
If necessary, change to the region where your resources are located. From the navigation bar, select the region that meets your needs. For more information, see Regions and Endpoints in the Amazon Web Services General Reference.
In the navigation pane, choose Metrics.
In the contents pane, select the metric that you want to add to your dashboard.
In the lower pane, choose Add to Dashboard.
In the Add to dashboard dialog box, in the Add to list, select the dashboard that you want to add the graph to, and then choose Add to dashboard.
To add other regions, metrics, or resources, repeat these steps as needed.
Choose Save dashboard.
