summary
Shows how to correlate Prometheus metrics and OpenTelemetry traces by converting OTLP metrics via the OpenTelemetry Collector into Prometheus format, storing both metrics and OTLP traces in Promscale (TimescaleDB), and querying with PromQL or SQL. Demonstrates jumping from histogram exemplars in Grafana straight to the trace, explains label/attribute alignment and type mapping (notes OpenTelemetry exponential histograms don’t map to Prometheus), and outlines using joins to find hosts, offending processes, and error-heavy spans.
