Microsoft Azure Architect Design (AZ-304) Practice Test 2025 - Free Azure Architect Exam Practice Questions and Study Guide

Application Insights is a powerful application performance management (APM) service that allows developers to monitor their applications in real-time. It provides deep insights into the application's performance, availability, and usage patterns. By integrating Application Insights into an Azure Service Fabric application, developers can harness advanced telemetry to collect data on exceptions, performance counters, and request rates.

This information enables them to proactively identify bottlenecks and other performance issues. The service automatically detects anomalies and can even provide intelligent insights into the potential causes of issues, helping teams address problems before they significantly impact the user experience. Application Insights also offers various visual tools and dashboards that guide developers in analyzing data trends, making informed decisions based on real-time metrics.

While other options, like container health, Azure Network Watcher, and Service Fabric Analytics, offer valuable insights and monitoring capabilities, they do not provide the same depth and immediate actionable intelligence for performance issues specifically tied to application operations as Application Insights does.
