Analyze multi-account app health with CloudWatch Application Insights

Customers can now monitor and troubleshoot application environments that span multiple accounts (within a region) using Amazon CloudWatch Application Insights. CloudWatch Application Insights helps customers gain actionable insights for their application environments by making it easier for them to set up and monitor, recognize problems, and use data to make decisions. With this release, customers can analyze and correlate cross-account telemetry data and problems through a centralized view of the monitoring results across their accounts.
