Knowing what’s happening together with your live web apps will build or break your client expertise. these days we tend to incessantly update and deploy our apps that are nice however it will generally end in performance or maybe functionality regression. we would like to proactively sight problems as before long as they occur and fix them before they begin poignant our users. Azure Application Insights will assist you to do this simply for any of your web app or services.
In this blog, I’ll offer you an outline tour of application insights & their core capabilities. We’ll additionally discuss however we will sight, sorting & diagnose all our real-world issues in our Web apps.

What Is Azure Monitor?
Azure Monitor is that the native observation resolution for Azure, and after we are exploiting Azure or doing something, it’s a gift within the background assembling information for you. Metrics and logs area unit collected by Azure monitor from all of your Azure resources and accustomed produce alerts, monitor, troubleshoot problems, performance and make dashboards so you’ve got full visibility of your Azure estate and a method to act once issues arise.

Why Monitoring Is Required?
Traditionally application observation has been an afterthought. we tend to accustomed not suppose monitoring before problems begin to pop up! however, with the present fashionable architectures like Microservices around several multi-tier applications out there, we want to infuse observation into our application development life-cycle from the offset, ranging from about to development, test, and unleash.
In that method, we will determine problems and optimizations needed as a part of the pre and post-production method and retell our calibration incessantly, and incidentally, that’s what DevOps is all about!

How Does Azure Monitor Work?
Azure Monitor collects observation measures from a range of on-premises and Azure sources. Management tools, like those in Azure Security Center and Azure Automation, additionally push log information to Azure Monitor. The service aggregates and stores this measure in a very log information store that’s optimized for price and performance. Analyze information, created alerts, get end-to-end views of your applications, and use machine learning-driven insights to quickly determine and resolve issues.
What Is Azure Application Insights?
Application Insights, a feature of Azure Monitor, is an extensile Application Performance Management (APM) service for developers and DevOps professionals.
- Use it to observe your live applications. it’ll mechanically sight performance anomalies and includes powerful analytics tools to assist you to diagnose problems and knowing what users really do together with your app.
- It’s designed to assist you incessantly improve performance and usefulness. It works for apps on a good type of platforms as well as .NET, Node.js, Java, and Python hosted on-premises, hybrid, or any public cloud.
- It integrates together with your DevOps method and has affiliation points to a range of development tools. It will monitor and analyze measures from mobile apps by group action with Visual Studio App Center.
How Do Application Insights Work?
You install a little instrumentation package (SDK) in your application or modify Application Insights exploitation of the appliance Insights Agent when supported. The instrumentation monitors your app and directs the measure information to an Azure Application Insights Resource employing a distinctive GUID that we tend to see as an Instrumentation Key.
You can instrument not solely the online service application, however additionally any background elements, and also the JavaScript within the sites themselves. the appliance and its elements will run anyplace – it does not have to be hosted in Azure.
In addition, you’ll be able to pull in measures from the host environments like performance counters, Azure diagnostics, or docker logs. You’ll be able to additionally created net tests that sporadically send artificial requests to your net service.
All these measure streams are integrated into Azure Monitor. Within the Azure portal, you’ll be able to apply powerful analytic and search tools to the raw data.
What Do Application Insights Monitor?
Azure 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 – decide that pages are most well-liked, at what times of day, and wherever your users are. See that pages perform best. If your response times and failure rates go high once their area unit additional requests, then maybe you’ve got a resourcing downside.
- Dependency rates, response times, and failure rates – decide whether or not external services are fastness you down.
- Exceptions – Analyze the collective statistics, or decide specific instances and drill into the stack trace and connected requests. each server and browser exception are rumored.
- Pageviews and load performance – reportable by your users’ browsers.
- AJAX calls from web pages – rates, response times, and failure rates.
- User and session count.
- Performance counters from your Windows or UNIX system server machines, like processor, memory, and network usage.
- Host diagnostics from Docker or Azure.
- Diagnostic trace logs from your app – so you’ll be able to correlate trace events with requests.
- Custom events and metrics you write yourself within the consumer or server code, to trace business events like things sold or games won.
Use Cases Of Application Insights?
- Detect and diagnose exceptions and application performance problems
- Get answers to your powerful queries, and take your applications to the following level
- Detect trends in application performance and behavior, determine usage patterns, and obtain quick answers to searching questions about your website performance
- Monitor Azure websites, as well as those hosted in containers, and websites on-premises and with alternative cloud providers
- Seamlessly integrate together with your DevOps pipeline exploitation Visual Studio Team Services (VSTS), GitHub, and webhooks
- Quickly start from inside Visual Studio, or monitor existing applications while not redeploying
How Do I Use Azure Application Insights?
Azure Application Insights can be used for Monitoring, Detecting, Diagnosing, Building, Measuring, and Learn. Let’s look at each of these in brief.
1. Monitor
Install Application Insights in your app, set up availability net tests, and:
- Check out the default application dashboard for your team space to stay an eye fixed on load, responsiveness, and also the performance of your dependencies, page loads, and mythical being calls.
- Discover that area unit the slowest and most failing requests.
- Watch Live Stream when you deploy a brand new unleash, to understand right away concerning any degradation.
2. Detect, Diagnose
When you receive an alert or discover a problem:
- Assess what percentage of users area unit affected.
- Correlate failures with exceptions, dependency calls, and traces.
- Examine profiler, snapshots, stack dumps, and trace logs.
3. Build, Measure, Learn
Measure the effectiveness of each new feature that you deploy.
- Plan to live however customers use new UX or business features.
- Write custom telemetry into your code.
- Base following development cycle onerous proof from your telemetry.
Steps To Monitor Machine Learning Models With Azure Application Insights
When you’ve deployed a model into production as a service, you’ll want to monitor it to track usage and explore the requests it processes. You can use Azure Application Insights to monitor activity for a model service endpoint.
- Connect to your Workspace: To get started, connect to your workspace
![]()
- Prepare a Model for Deployment
- Deploy a Model as a Web Service
- Now you need an entry script that the service will use to score new data
- You’ll also need a Conda configuration file for the service environment.
- Enable Azure Application Insights: Next, you need to enable Application Insights for the service.
- Use the Web service: With the service deployed, now you can consume it from a client application.
First, determine the URL to which these applications must submit their requests.
Conclusion
The Azure monitoring services help to monitor resources, you can easily monitor your resources with various monitoring services provided by Azure. With Application Insights, there is no upfront cost, no termination fees, and you only pay for what you need. The blog clears the concepts in more detail like how monitoring services work and how they look and are easy to manage.
