From Manual Trace Queries to Intelligent Link Analysis at Million‑QPS Scale

The article walks through how link tracing evolves from manually searching individual traces to an automated, intelligent system that aggregates massive spans, derives RED metrics and service maps, performs critical‑path and differential analysis, auto‑detects anomalies, and ties together traces, metrics, and logs for rapid root‑cause identification.
