Microsoft Azure Developer Associate AZ-204 Practice Question
During a stress-test of an ASP.NET Core web API that is instrumented with Application Insights, you want to observe incoming request rate, request failure percentage, and dependency call duration in near real-time so you can decide when to stop the test. You do not want to wait for the normal five-minute metric aggregation cycle or run repeated log queries. Which Application Insights feature should you open in the Azure portal?
Live Metrics Stream bypasses the normal aggregation pipeline by streaming telemetry samples from the SDK directly to the portal with a latency of only a few seconds. It surfaces real-time counters such as request rate, request failures, dependency duration, and CPU/memory usage, making it ideal for monitoring under load tests or live incident response. The Failures blade, Application Map, and Metric Explorer rely on back-end aggregation and can lag by several minutes; they are better suited for post-analysis than real-time observation.
