What is Azure Application Insights?
Developers and DevOps specialists can use Application Insights, an attribute of Azure Monitor, as an extensible Application Performance Management (APM) service.
You can use it to monitor your running programs. It will automatically detect performance anomalies and come with strong analytics capabilities to help you solve issues and understand how users actually use your app.
It is built in such a way to help you continuously increase performance and utility. It works for apps running on various solid platforms, including.NET, Node.js, Java, and Python, whether hosted on-premises, in a hybrid environment or in a public cloud.
It offers connection points to a variety of development tools and connects with your DevOps methodology. You can easily track and analyze measures from mobile apps through collective action with Visual Studio App Center.
How does Azure App Insights Work?
You can change Application Insights’ exploitation of the appliance Insights Agent when supported. You can also install an SDK in your application. The instrumentation tracks your app’s performance and sends the data to an Azure Application Insights resource using a unique GUID that we refer to as an instrumentation key.

What Azure Application Insights Monitors
- Azure App Insights report different exceptions depending on your servers and browsers.
- It provides you with information on requests and failure rates.
- The speed of response.
- It gives you access to your applications’ trace logs.
- Your browser’s functionality.
- Your sessions and users are counted.
- It also tells how your server machines use their networks, memory, and CPU.
- Exceptions – Examine the overall statistics, pick out particular cases, and delve deeper into the stack trace and related requests. There are rumours about each server and browser exception.
- Browsers used by your users can report page views and load performance.
- You can quickly get rates, delays, and failure rates for AJAX requests sent from web pages.
- Count of users and sessions.
- Host diagnostics coming from Azure or Docker.
- Your app’s diagnostic trace logs will allow you to connect trace events to requests.
- You create your own custom metrics and events within the client or server code to track commercial events like sales or wins.
Azure Application Insights Features
These are some of the best features for Azure App Insights:
1. Application Performance
Specific application performance statistics, such as response rates, exception rates, failure rates, and page-load durations, can be gathered by Application Insights.
Additionally, you may get host diagnostics data from the Azure platform, performance counters (CPU, memory, and network usage) from Windows/Linux servers, containerized workloads that aid in locating application bottlenecks, and data from Windows/Linux servers’ CPU, memory, and network consumption.
Application Insights aids in the capturing of errors involving both the server and the browser and offers deeper investigation through stack traces.
2. Application Usage
The detailed analytics provided by App Insights assist you in analyzing user interaction through data such as the most popular sites and peak access hours. It helps you better understand application usage is user and session count data.
Also, identifying underlying resource limitations will be assisted by correlating usage statistics with application performance measurements.
3. Custom Monitoring
You can create custom code and events to track particular application events using Application Insights in addition to the built-in metrics. You can monitor, for instance, the acceptance of a new product feature or the trends surrounding a specific product.
4. Application Availability
You can set up Application Insights to run ping tests or web requests to verify the availability of your applications. By using the SDK, you can combine any existing custom applications you may have for tracking availability with Application Insights. You can create Alerts and the unavailability of applications. You can also note any delays in application response time.

How to Create Azure Application Insights?
Some of the requirements to use Azure App Insights are:
Prerequisites: You must have an Azure account or subscription. If you don’t have a Microsoft Azure account then check out this blog on how to create Microsoft Azure free account.
Let’s begin with the steps to establish Azure Application Insights.
1. Open the Azure Portal and login.
2. Click the “Application Insights” search result after conducting a search for it.
3. To create the Azure application Insights resource, click the + Create or Create Application Insights app buttons.
4. Give the information below in the Application Insights window.
- Subscription: A valid Azure subscription should be selected in order to construct the Application Insights.
- Resource Group: To create a new Resource Group, choose the Create a new link or an existing resource group from the list.
- Name: Give your Azure Insights a distinctive name.
- Region: Choose a region or a location.
- Resource Mode: Choose this option.
- Subscription: Choose a legitimate Azure subscription under Subscriptions.
- Log Analytics Workspace: Use the default workspace or pick one that is already set up.
Click the Review + Create button after that.
5. The next screen will now validate all the information you supplied and display the message “Validation Passed.” In order to construct the Azure Insight Analytics, click the Create button.
It will take a little while before it notifies you that your deployment is finished. To access the Azure Insight Analytics you’ve generated, click the Go to resource option.
How to Enable Application Insights for your Web App?
You should follow the instructions below to enable Application Insights for your web applications:
1. Navigate to the Overview tab in your Web App’s Azure Portal window.
2. Select the below-highlighted Application Insights option. It might occasionally be turned on by default for you.
3. Alternatively if you can see the “Turn on Application Insights” button. To enable Application Insights for your WebApp, click that.
If you want to use App Insights to gather application monitoring data, you can select Enable. Expand the resource change option.
4. You can create a new Azure App Insights resource. Alternatively, one can pick an existing Application Insight resource.
Select the “Create a new resource” option to start a new resource.
- A New Resource: Give your resource a special name.
- Place: Pick a region or location.
- Log Analytics Workspace: You can either select the default workspace or the Log Analytics workspace.
5. When you reach the Instrument, your application part, scroll down a little bit. Depending on the nature of your application and your needs, you can select among tabs like.Net,.Net Core, Node.js, Jave, Python, etc.
