Azure Web Apps (classic) Test

Azure Websites is a managed cloud service that allows you to deploy a web application and make it available to your customers on the Internet in a very short amount of time. You don’t directly support the VMs on which your website runs; they are managed for you. By hosting the websites on the cloud, administrators can be freed from managing the physical infrastructure required to run the websites. Though the website is hosted on the Azure cloud through the Azure Resource Manager, it is important for an administrator to constantly monitor the availability and resource utilization of the websites. The Azure Web Apps test helps administrators in this regard.

By constantly monitoring the website hosted on the cloud, administrators can figure out the availability of the website, runtime availability of the website, erroneous websites and the websites that are over-utilizing the resources allocated to them. This way, administrators can be assured of the availability of the websites.

This test is disabled by default.
