Amazon OpenSearch Service supports Managed Prometheus and agent tracing

Amazon OpenSearch Service now provides a unified observability experience that brings together metrics, logs, traces, and AI agent tracing in a single interface. This release introduces native integration with Amazon Managed Service for Prometheus and comprehensive agent tracing capabilities, addressing the dual challenges of prohibitive costs from premium observability platforms and operational complexity from fragmented tooling. Site Reliability Engineers, DevOps Engineers, and Platform Engineering teams can now consolidate their observability stack without costly data duplication or constant context switching between multiple tools. You can now query Prometheus metrics directly using native PromQL syntax alongside logs and traces in OpenSearch UI's observability workspace—without duplicating data. Combined with new application monitoring workflows powered by RED metrics (Rate, Errors, Duration) and AI agent tracing using OpenTelemetry GenAI semantic conventions, operations teams can correlate slow traces to application logs, overlay Prometheus metrics on service dashboards, and trace LLM agent execution—all without switching tools. This live query architecture delivers significant cost reduction compared to premium platforms while maintaining operational excellence. The new unified observability experience is available on OpenSearch UI in 20 AWS regions: US East (N. Virginia, Ohio), US West (N. California, Oregon), Asia Pacific (Hong Kong, Mumbai, Osaka, Seoul, Singapore, Sydney, Tokyo), Europe (Frankfurt, Ireland, London, Milan, Paris, Spain, Stockholm), Canada (Central), and South America (São Paulo).
