Azure Application Insights

Application Insights can monitor Azure cloud service apps for availability, performance, failures, and usage by combining data from Application Insights SDKs with Azure Diagnostics data from your cloud services. With the feedback you get about the performance and effectiveness of your app in the wild, you can make informed choices about the direction of the design in each development lifecycle.

Application Insights, a feature of Azure Monitor, is an extensible Application Performance Management (APM) service for developers and DevOps professionals. Use it to monitor your live applications. It will automatically detect performance anomalies and includes powerful analytics tools to help you diagnose issues and understand what users actually do with your app. It's designed to help you continuously improve performance and usability. It works for apps on various platforms, including .NET, Node.js, Java, and Python hosted on-premises, hybrid, or any public cloud. It integrates with your DevOps process and has connection points to a variety of development tools. It can monitor and analyze telemetry from mobile apps by integrating with Visual Studio App Center.
