Azure Application Insights
Azure Application Insights is an application performance management (APM) service within Microsoft Azure that provides deep insights into the performance, availability, and usage of web applications. It collects telemetry data such as requests, dependencies, exceptions, and traces to help developers monitor, diagnose, and optimize applications in real-time. It integrates seamlessly with Azure services and supports various programming languages and frameworks.
Developers should use Azure Application Insights when building and maintaining cloud-based applications on Azure to gain visibility into performance bottlenecks, detect failures proactively, and understand user behavior. It is particularly valuable for distributed systems, microservices architectures, and DevOps workflows, enabling quick troubleshooting and data-driven improvements. Use cases include monitoring web apps, APIs, and background jobs, as well as setting up alerts for critical issues.
