What problem does it solve?

Cross-signal correlation across traces, logs, and metrics using OpenTelemetry semantics to enable end-to-end observability investigations.

Core Features & Use Cases

  • Correlate traces, logs, and metrics by shared fields like traceId, spanId, and resource attributes to reconstruct end-to-end requests across OpenTelemetry data.
  • Use PPL queries in OpenSearch and Prometheus exemplars to surface cross-signal context for debugging and performance analysis.
  • Use case: identify a spike in latency, trace it to the failing span, and surface the related logs for root-cause analysis.

Quick Start

Use OpenSearch PPL and Prometheus exemplars to surface linked traces, logs, and metrics for a given service.
