Amazon CloudWatch RUM is now generally available in the two GovCloud regions

Amazon CloudWatch RUM, which enables customers to monitor their web applications by collecting client side performance and error data in real time, is additionally available in the following AWS Regions starting today: AWS GovCloud (US-East), and AWS GovCloud (US-West).

CloudWatch RUM provides curated dashboards for web application performance experienced by real end users including anomalies in page load steps, core web vitals, and JavaScript and HTTP errors across different geolocations, browsers, and devices. Custom events and metrics sent to CloudWatch RUM can be easily configured to monitor specific parts of the application for real user interactions, troubleshoot issues, and get alerted for anomalies. CloudWatch RUM comes integrated with the application performance monitoring (APM) capability, CloudWatch Application Signals. As a result, client-side data from your application can easily be correlated with performance metrics such as errors, faults, and latency observed in your APIs (service operations) and dependencies to address the root cause.

To get started, see the RUM User Guide. Usage of CloudWatch RUM is charged on the number of collected RUM events, which refers to each data item collected by the RUM web client, as detailed here.
