Application Insights for apps in Azure - Mini Project: Build & Apply

Application Insights for apps

📖 Scenario: You are working on a cloud application hosted in Azure. You want to monitor its performance and usage by setting up Application Insights. This will help you see how your app is doing and find any problems quickly.

🎯 Goal: Set up Application Insights for an Azure web app by creating the resource, configuring the instrumentation key, and enabling monitoring.

📋 What You'll Learn

Create an Application Insights resource with the exact name MyAppInsights

Create a variable called instrumentation_key to hold the instrumentation key from the resource

Configure the Azure web app to use the instrumentation_key

Enable Application Insights monitoring on the Azure web app

💡 Why This Matters

🌍 Real World

Application Insights helps developers and operators monitor live applications to detect issues and understand usage patterns.

💼 Career

Knowing how to set up and configure Application Insights is a key skill for cloud engineers and developers working with Azure apps.

1

Create Application Insights resource

Create an Application Insights resource in Azure with the exact name MyAppInsights using Azure CLI command az monitor app-insights component create.

Azure

# Your code here to create Application Insights resource named MyAppInsights

Need a hint?

Use az monitor app-insights component create with --app MyAppInsights to create the resource.

2

Get instrumentation key

Create a variable called instrumentation_key and assign it the instrumentation key value from the Application Insights resource MyAppInsights using Azure CLI.

Azure

az monitor app-insights component create --app MyAppInsights --location eastus --resource-group MyResourceGroup --application-type web
# Your code here to get instrumentation key and assign to variable instrumentation_key

Need a hint?

Use az monitor app-insights component show with --query instrumentationKey to get the key.

3

Configure web app with instrumentation key

Use Azure CLI to set the application setting APPINSIGHTS_INSTRUMENTATIONKEY on the Azure web app named MyWebApp in resource group MyResourceGroup to the value of the variable instrumentation_key.

Azure

az monitor app-insights component create --app MyAppInsights --location eastus --resource-group MyResourceGroup --application-type web
instrumentation_key=$(az monitor app-insights component show --app MyAppInsights --resource-group MyResourceGroup --query instrumentationKey -o tsv)
# Your code here to set APPINSIGHTS_INSTRUMENTATIONKEY on MyWebApp

Need a hint?

Use az webapp config appsettings set to add the instrumentation key setting.

4

Enable Application Insights monitoring

Enable Application Insights monitoring on the Azure web app MyWebApp in resource group MyResourceGroup by linking it to the Application Insights resource MyAppInsights using Azure CLI.

Azure

az monitor app-insights component create --app MyAppInsights --location eastus --resource-group MyResourceGroup --application-type web
instrumentation_key=$(az monitor app-insights component show --app MyAppInsights --resource-group MyResourceGroup --query instrumentationKey -o tsv)
az webapp config appsettings set --name MyWebApp --resource-group MyResourceGroup --settings APPINSIGHTS_INSTRUMENTATIONKEY=$instrumentation_key
# Your code here to enable Application Insights monitoring on MyWebApp

Need a hint?

Use az webapp update to finalize enabling monitoring if needed.
