Microsoft Azure App Service plan acts as platform-as-a-service (PaaS) offering that enables you to host web apps, RESTful APIs, and mobile back ends. It defines a set of compute resources for a web app to run. App Service Plans supports multiple programming languages and frameworks like .NET, Java, Ruby, Node.js, PHP, and Python and allows you to deploy your applications in data centers across the globe. Monitoring Azure App Service Plan is crucial to track the performance level of the App service plans and thus maintain them with ease. Learn more about how Applications Manager's Azure App Service Plan monitoring tool helps in achieving it.

Navigate to the Category View by clicking the Monitors tab. Hover over 'Child Monitors' under Microsoft Azure in the Cloud Apps table, and then select the App Service Plans monitor from the displayed tooltip. This action will display the bulk configuration view for Azure App Service Plan in three tabs:
The Microsoft Azure monitor provides a brief detail of the Azure App Service Plan under the given subscription. Following are the list of metrics monitored in Azure App Service Plan Monitoring in their corresponding tabs:
