What is Jaeger Tracing and How does It Locate Slowdowns Across Microservices
Why does a checkout or login take several seconds when CPU and memory look normal on every server? In microservices, one click can travel through a long chain of components before the user sees a response. Any one of them can hold the request up, and server graphs won't tell you which. Logs show what each service recorded. Metrics give you averages. What's missing is the path one request took and the place it lost time, and Jaeger tracing records exactly that.
