Amazon OpenSearch Service Optimized Engine Now Supports Agent Traces
AWS, Thursday, November 5th, 2026
Amazon OpenSearch Service optimized engine now supports agent traces, including OpenTelemetry traces, alongside logs.
The Amazon OpenSearch Service optimized engine now supports agent traces, including OpenTelemetry traces, so traces and logs live in one place for following a request or agent session end to end.
The engine maps OpenTelemetry data to object, nested, and flat object fields, preserving the nested structure of span events, span links, prompts, and tool calls for field-level queries.
On hot-tier data it supports update, delete, and upsert by document ID to correct late or erroneous data in place.
OpenSearch UI offers Discover Traces, application performance monitoring, a service map, and agent traces and sessions views, available on OpenSearch 3.7 at no extra charge in 12 AWS Regions.
