⚡ Lightning Talk: From HAR To OpenTelemetry Trace: Redefining Your Observability
Lightningat Observability Day 2025 · on Tuesday, 2025-04-01· at 17:15· Level 1 | Hall Entrance S10 | Room B·
summary
Converts HAR page‑load output from ThousandEyes into OpenTelemetry traces and streams them to Jaeger via Kafka and two dedicated collectors, one that converts and enriches HAR into spans and another that routes per‑integration to multiple observability backends. Each HTTP request becomes a span with autogenerated trace/span IDs, semantic attributes (method, host, URL, status) and headers omitted for security. Demo shows traces in Jaeger, enables comparing traces and spotting tens of extra spans (example ~45) and multi‑second regressions.
