Application Insights is an extensible Application Performance Management (APM) service for web developers. It provides in-depth insights into your applications, helping you detect and diagnose issues, track performance, and gain actionable insights for improving application performance and user experience. With Application Insights, you can easily monitor your application’s availability, performance, and usage, and identify and troubleshoot problems before they affect your users.
- Detailed telemetry: Application Insights collects and analyzes data about your application’s availability, performance, usage, and exceptions. It provides detailed telemetry, including metrics, events, logs, and traces, to help you monitor and troubleshoot your application effectively.
- Real-time monitoring: With real-time monitoring, you can quickly identify and respond to issues as they occur. Application Insights provides live metrics and diagnostics, allowing you to visualize and analyze real-time data to gain insights into the health and performance of your application.
- Alerts and notifications: Stay on top of critical issues with the ability to create alerts and receive notifications based on custom-defined conditions. Application Insights enables you to set up alerts for essential metrics, exceptions, availability changes, and more.
- Deep diagnostics: Identify and diagnose application problems with deep diagnostic tools, including detailed exception traces, request tracking, code-level performance profiling, and dependency tracing. These tools help you pinpoint the root cause of issues and optimize your application’s performance.
- Integration with development tools: Application Insights seamlessly integrates with popular development tools such as Visual Studio, Azure DevOps, and GitHub, providing a unified workflow for monitoring and troubleshooting your applications.
Follow the steps below to get started with using Application Insights in your application:
- Create an Application Insights resource: In the Azure portal, create a new Application Insights resource or use an existing one.
- Install the Application Insights SDK: Install the Application Insights SDK for your preferred platform or programming language. The SDK enables your application to send telemetry data to Application Insights for analysis and monitoring.
- Instrument your application: Add instrumentation code to your application to start collecting telemetry. Depending on your application’s platform and language, this step may involve adding a few lines of code or configuring settings.
- View and analyze data: Once your application starts sending telemetry, you can use the Application Insights portal to view and analyze your application’s data. The portal provides various tools and visualizations to help you gain insights into your application’s performance, usage, and exceptions.
- Set up alerts and notifications: Configure alerts and notifications to be proactively notified about critical issues or abnormal behavior detected by Application Insights.
- Monitor and optimize: Continuously monitor your application’s health and performance, investigate any anomalies, and optimize your application based on insights gained from Application Insights.
