summary
OpenTelemetry’s collector and SDKs capture traces, metrics, logs and resource metadata and let back ends correlate them so investigations jump from service topology to host metrics to logs tied to a single request. A Hipster Shop demo shows 8.4s 90th‑percentile checkout latency traced to repeated payment calls caused by an invalid API token causing repeated retries, with a secondary issue of Postgres 672ms 99th; correlations rely on trace/span IDs stamped into logs and work end‑to‑end.
