To verify that your Web App is running in the Azure Portal, follow these steps to ensure that it is properly deployed and accessible:
Here are the steps to verify a Web App is Running in the Azure Portal.
Step 1. Check the Web App Overview in Azure Portal
Log in to Azure Portal:
Go to the and log in with your credentials.
Navigate to Your Web App:
In the Azure Portal, in the left-hand navigation pane, click on "App Services".
This will show a list of all the App Services in your subscription.
Locate and click on the name of the Web App you created earlier.
Overview Tab: Once inside your Web App’s resource page, go to the Overview tab. This page provides a summary of the web app's current status. In the Overview section, you should see the following details:
App URL: The URL of your web app, typically in the format
yourappname.azurewebsites.net.You can click this link to open the app in a browser.
Resource Group: The name of the resource group to which your web app belongs.
Status: The current state of your app (e.g., "Running").
Status: Ensure that the status shows as "Running" (if it's not running, you can start or restart the app here).
Access the Web App:
Click on the App URL shown in the Overview section to open your web app in a browser.
If the app is running correctly, the app's homepage or default page should be displayed in the browser.
Step 2. Verify App Health and Logs
App Service Health:
In the Overview tab, you can also check the Health status of your app.
If the app isn't responding correctly, Azure will typically flag it as "Unhealthy".
In the Monitoring section on the left, click "App Service Plan" to verify if the hosting environment (the plan) is healthy and operating as expected.
Check the Logs:
In the left sidebar, under the Monitoring section, click on "Logs".
If you have enabled Application Insights during the setup, you can see live metrics, failures, and request logs here.
If not, you can enable Application Insights to gather telemetry data to help you diagnose issues with your app.
Check Diagnostic Logs:
Under Monitoring in the left sidebar, click on "Diagnose and solve problems".
This feature will help you identify issues with your app, such as configuration problems, performance bottlenecks, or code failures.
You can also go to "Log stream" to view live log output from your web app (e.g., requests, errors, and exceptions).
This is helpful for real-time diagnostics.
Step 3. Verify App Service Plan and Scaling
Check the App Service Plan:
Ensure that your app is running under an active App Service Plan with sufficient resources (e.g., CPU, memory, and scaling settings).
Go to the App Service Plan under the Settings section on the left-hand side.
Verify that the plan has enough resources and is not in a stopped or scaled-down state.
Scale Up or Out:
If your app is not performing as expected (e.g., slow performance), you can check the scaling settings.
To scale, go to the Scaling section (within the App Service Plan settings), and choose either to scale up (increase the resources, such as CPU or RAM) or scale out (increase the number of instances).
Make sure the scaling settings are correct for your app's workload.
Step 4. Check Web App Health Using Kudu Console
If the app isn’t running as expected and you need to investigate further:
Access the Kudu Console:
In the Azure Portal, go to your App Service and, under the Development Tools section on the left, click on "Advanced Tools".
Click on Go, which will open the Kudu Console.
Check App Files and Logs:
From the Kudu Console, you can access the app’s files and logs.
Navigate to the Debug console (CMD or PowerShell) and check the
D:``\``home``\``LogFilesdirectory for logs related to your app’s runtime and performance.You can also use this console to explore your web app’s file system or diagnose problems with the application directly.
Step 5. Restart the Web App (If Needed)
Sometimes, simply restarting the web app can resolve issues like a service crash or a configuration update not being applied correctly.
Restart:
In the Overview tab of your app’s page, click the Restart button at the top of the page to restart the web app.
This can help clear any temporary issues or hangups with the app.
Step 6. Check Deployment Source for Issues
If you’re using continuous deployment (via GitHub, Azure Repos, etc.), ensure the deployment source is working as expected:
Go to the Deployment Center section under Settings to verify the deployment pipeline.
Check for any recent errors or failed deployments.
Verify that your code was deployed successfully by checking the deployment logs.
Step 7. Use Azure Monitor (Optional)
If you're still unsure whether your app is fully operational or you need more detailed insights:
Azure Monitor:
Set up Azure Monitor for detailed telemetry, such as request counts, error rates, and resource utilization.
Go to Monitoring > Insights or Monitoring > Application Insights to view these metrics.
Summary
Overview: Check if the web app is running by looking at the status and the app URL.
Logs: Use the Logs and Diagnose and solve problems sections for troubleshooting and to view application performance.
Scaling: Verify that the app is running under an appropriate App Service Plan and ensure that scaling settings are configured correctly.
Kudu Console: Use the Kudu Console to access your app's files and diagnose issues.
Restart: Restart your web app if needed to resolve minor issues.
Deployment Center: Check deployment logs if you're using continuous deployment to ensure code is properly deployed.
Azure Monitor: Set up or check Azure Monitor and Application Insights for deeper diagnostics and telemetry.
By following these steps, you should be able to confidently verify that your web app is running in Azure and troubleshoot any potential issues.
