Ensure that Application Insights feature is enabled for all your Microsoft Azure App Services web applications in order to provide advanced application monitoring. Application Insights is an extensible Application Performance Management (APM) service for developers and DevOps professionals available as monitoring feature within Azure cloud. The feature monitors your live App Services applications to automatically detect performance anomalies. Application Insights includes powerful analytics tools that help you diagnose issues and understand what the end users actually do with your application. Application Insights can be enabled for apps on a wide variety of platforms including .NET, Node.js and Java EE, hosted on-premises, hybrid, or any other public cloud platforms. It seamlessly integrates with your DevOps processes and has connection points to a variety of development tools.
Application Insights can monitor the following:
Request rates, response times and failure rates - find out which web pages are the most popular, at what times of the day, and where your end users are. Also, find out which pages perform best.
Dependency rates, response times and failure rates - find out whether external services are slowing down your web application.
Server and browser exceptions - analyze the aggregated statistics available or pick specific instances and drill into the stack trace and related requests.
Page views and load performance - performance data reported by the end users' browsers.
AJAX calls from web pages - rates, response times and failure rates.
User and session counts.
Performance counters from your Linux or Windows virtual machines, such as CPU, memory and network usage.
