Hello everyone,

Today, I’m gonna write a bit about Azure Application Insights which is one of the features of Azure Monitor service, hope it’ll be helpfull.

Application Insights, a feature of Azure Monitor, monitors your live applications. It will automatically
detect performance anomalies, and includes powerful analytics tools to help you diagnose issues and to
understand what users actually do with your app. It’s designed to help you continuously improve performance
and usability. It works for apps on a wide variety of platforms including .NET, Node.js and Java EE,
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.

Application Insights features

Application Insights is aimed at the development team, to help you understand how your app is performing
and how it’s being used. It monitors:

●● Request rates, response times, and failure rates – Find out which pages are most popular, at what
times of day, and where your users are. See which pages perform best. If your response times and
failure rates go high when there are more requests, then perhaps you have a resourcing problem.

●● Dependency rates, response times, and failure rates – Find out whether external services are
slowing you down.

●● Exceptions – Analyze the aggregated statistics, or pick specific instances and drill into the stack trace
and related requests. Both server and browser exceptions are reported.

●● Page views and load performance – reported by your users’ browsers.

●● User and session counts.

●● Performance counters from your Windows or Linux server machines, such as CPU, memory, and
network usage.

●● Host diagnostics from Docker or Azure.

●● Diagnostic trace logs from your app – so that you can correlate trace events with requests.

●● Custom events and metrics that you write yourself in the client or server code, to track business
events such as items sold or games won.
