Microsoft Azure Developer Associate AZ-204 Practice Question
You are stress-testing a production ASP.NET Core app in Azure App Service that is already instrumented with Application Insights. You must see, in under five seconds, how many requests are failing and whether a specific instance is at fault, without writing Kusto queries or waiting several-minute ingestion delays. Which Application Insights blade should you open?
Live Metrics Stream (also called QuickPulse) streams lightweight, pre-aggregated telemetry every second directly from each running instance. It displays request rate, failure rate, response time, and CPU/memory counters, and it can be filtered per instance, giving visibility almost immediately after events occur. Other blades such as Failures or Logs rely on the standard telemetry pipeline, which typically adds minutes of latency; Availability tests show synthetic probe results, and Smart Detection only sends automated alerts, not real-time charts.
