AWS launches CloudWatch Omni to unify observability for AI agents and applications

AWS CloudWatch Omni unifies agent, application, and infrastructure observability in a single pane, directly addressing the visibility gap that keeps enterprises from moving AI agents from pilots to production. Early adopters are existing CloudWatch/Bedrock customers; broader enterprise adoption depends on teams willing to consolidate on AWS's observability stack.
