Amazon CloudWatch RUM now supports monitoring multiple domains with a single App Monitor

Amazon CloudWatch RUM now allows customers to monitor multiple top-level domains (TLDs), and second-level domains (SLDs) using a single App Monitor unifying real user monitoring across multiple domains in CloudWatch RUM. Customers can now specify a list of domains and also use wildcards for TLDs to monitor all their front-end applications together. This enhancement is useful for web applications that need to be accessible from different domains due to various reasons such as user locations, domain migrations, or any other development needs.

This enhancement simplifies observability for applications accessed from multiple domains by displaying all real user data of the application on a single RUM dashboard. Customers can now monitor different SLDs, such as example.com and another.com, without creating separate monitors for each domain. They can also track applications deployed across multiple TLDs, such as example.com, and example.co.uk, helping monitoring performance across regions. Wildcard support for TLDs allows customers even more flexibility to monitor all variants of a domain, such as example.* or example.co.*, without manually specifying each one. Additionally, subdomain wildcards, which is already supported, continue to allow monitoring across multiple subdomains like *.example.com. These capabilities simplifies monitoring websites that operate in multiple regions, manage domain transitions during SLD migrations, and other development needs by consolidating data in a single place.

This feature is now available in all AWS commercial regions where CloudWatch RUM is available.
