Create an Application Insights resource

Azure Application Insights displays data about your application in a Microsoft Azure resource. Creating a new resource is therefore part of setting up Application Insights to monitor a new application. After you have created your new resource, you can get its instrumentation key and use that to configure the Application Insights SDK. The instrumentation key links your telemetry to the resource.


On February 29th, 2024, support for classic Application Insights will end. Transition to workspace-based Application Insights to take advantage of new capabilities. Newer regions introduced after February 2021 do not support creating classic Application Insights resources.


On March 31, 2025, support for instrumentation key ingestion will end. Instrumentation key ingestion will continue to work, but we'll no longer provide updates or support for the feature. Transition to connection strings to take advantage of new capabilities.

Create an Application Insights resource

Sign in to the Azure portal, and create an Application Insights resource:

Click the + sign in the upper left corner. Select Developer Tools followed by Application Insights

Settings Value Description
Name Unique value Name that identifies the app you are monitoring.
Resource Group myResourceGroup Name for the new or existing resource group to host App Insights data.
Region East US Choose a location near you, or near where your app is hosted.
Resource Mode Classic or Workspace-based Workspace-based resources allow you to send your Application Insights telemetry to a common Log Analytics workspace. For more information, see the article on workspace-based resources.


While you can use the same resource name across different resource groups, it can be beneficial to use a globally unique name. This can be useful if you plan to perform cross resource queries as it simplifies the required syntax.

Enter the appropriate values into the required fields, and then select Review + create.

Enter values into required fields, and then select "review + create".

When your app has been created, a new pane opens. This pane is where you see performance and usage data about your monitored application.

Copy the instrumentation key

The instrumentation key identifies the resource that you want to associate your telemetry data with. You will need to copy the instrumentation key and add it to your application's code.

Install the SDK in your app

Install the Application Insights SDK in your app. This step depends heavily on the type of your application.

Use the instrumentation key to configure the SDK that you install in your application.

The SDK includes standard modules that send telemetry without you having to write any additional code. To track user actions or diagnose issues in more detail, use the API to send your own telemetry.

Creating a resource automatically


Create a new Application Insights resource

New-AzApplicationInsights [-ResourceGroupName] <String> [-Name] <String> [-Location] <String> [-Kind <String>]
 [-Tag <Hashtable>] [-DefaultProfile <IAzureContextContainer>] [-WhatIf] [-Confirm] [<CommonParameters>]


New-AzApplicationInsights -Kind java -ResourceGroupName testgroup -Name test1027 -location eastus


Id                 : /subscriptions/{subid}/resourceGroups/testgroup/providers/microsoft.insights/components/test1027
ResourceGroupName  : testgroup
Name               : test1027
Kind               : web
Location           : eastus

For the full PowerShell documentation for this cmdlet, and to learn how to retrieve the instrumentation key consult the Azure PowerShell documentation.

Azure CLI (preview)

To access the preview Application Insights Azure CLI commands, you first need to run:

 az extension add -n application-insights

If you don't run the az extension add command, you will see an error message that states: az : ERROR: az monitor: 'app-insights' is not in the 'az monitor' command group. See 'az monitor --help'.

Now you can run the following to create your Application Insights resource:

az monitor app-insights component create --app


az monitor app-insights component create --app demoApp --location westus2 --kind web --resource-group demoRg --application-type web


az monitor app-insights component create --app demoApp --location eastus --kind web --resource-group demoApp --application-type web
