Profile & Monitor Web Apps with Azure Application Insights
summary
Shows how to add Azure Application Insights to web apps (install the .NET Core SDK package plus the separate profiler package and set the instrumentation key), where it sits in front of DB/storage/APIs, and how to use Application Map and Distributed Tracing to find slow components. Demonstrates profiler captures (sampling) that reveal a 10.2s request where component calls total ~1s and profiler sampling exposes ~9s of intentional wait, examples like a 14s external API call with 10s sleep, and notes profiling needs App Service plan Basic+ and can auto-trigger (CPU threshold ~80%, 120s default).
