In the Azure Portal, you manage your web apps through a series of blades, which are containers for the different components. (For an overview of the Azure Portal, please refer to the Portal changes guide.)
To view the blade for your web app, click Home and then the app name, or click Browse to see all of your Azure resources.
The top part of the blade has controls for some common actions:
Settings to see a list of all management settings.
Browse to open the web app in browser window.
Other buttons start or stop the app, swap deployment slots, delete the app, and so forth.
Essentials lists basic information about the app, including URL, location, App Service plan, and current status (running, stopped, etc).
Below Essentials are various parts that you can use to monitor, manage, and deploy your app. To customize the layout of blade, right click and select Customize or Add Parts. The rest of this topic describes the parts in the default layout.
Under Monitoring is a graph that shows metrics for your web app. To configure the graph, click Edit. You can select the time range and which metrics to display. Available metrics include number of requests, average response time, server errors, and CPU time.
To add an alert rule, click the graph, then click Add alert. An alert rule notifies you when a particular metric reaches some threshold. For example, you can be alerted when the number of server errors exceeds some value over a 5-minute period.
Monitoring also includes parts to configure analytics, set up application monitoring, and create availability tests. For more information, see Monitoring basics for Web Apps in Azure App Service.
If you want to get started with Azure App Service before signing up for an Azure account, go to Try App Service, where you can immediately create a short-lived starter web app in App Service. No credit cards required; no commitments.
