Monitor and observe apps across multiple accounts with Application Signals

CloudWatch Application Signals, an application performance monitoring (APM) tool that simplifies health and performance monitoring for applications now supports the ability to monitor your applications' services and Service Level Objectives (SLOs) across multiple source accounts from one monitoring account. Centralized application observability across accounts in a region provides single-pane-of-glass tracking, health maintenance, and resource optimization. Customers can use Amazon CloudWatch Observability Access Manager (OAM) to create and manage links between source accounts and monitoring accounts. Using the Application Signals Console in their monitoring account, customers can now view all services and SLOs to analyze and track broad patterns across multiple accounts. They can also set SLOs in the monitoring account. The multi account monitoring feature balances centralized monitoring with access restrictions required by their teams. Cross Account support for Application Signals is available in all [regions where Application Signals](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Application-Monitoring-Sections.html) is generally available. See [documentation](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Unified-Cross-Account.html) to learn more.
