Application Insights
Application Insights is a feature of Microsoft Azure that provides application performance management (APM) and monitoring for web applications and services. It collects telemetry data such as requests, dependencies, exceptions, and performance metrics to help developers diagnose issues, understand user behavior, and optimize application performance. It integrates with various development frameworks and supports both cloud and on-premises deployments.
Developers should use Application Insights when building and maintaining applications on Azure or in hybrid environments to gain deep insights into application health and performance. It is particularly valuable for monitoring production applications, detecting and diagnosing performance bottlenecks, tracking user engagement, and setting up alerts for critical issues. Use cases include monitoring web apps, APIs, microservices, and mobile backends to ensure reliability and improve user experience.
