This page applies to the .NET Agent in the Azure App services environment. It describes how the .NET Agent names your virtual application tiers and nodes by default, and how to customize the names of tiers.

An Azure Web App consists of the main application and its sub-applications. Together, these applications are called "virtual applications". Once you instrument an Azure Web App with the .NET Agent, restart the application and apply load to it, the .NET Agent reports metrics for the application and virtual applications. The .NET Agent names your virtual application tiers using either a default or custom method:

• Default: Splunk AppDynamics creates new tiers for each virtual directory. Each tier contains a node representing the virtual directory.
• Custom: When you specify a tier name in the AppDynamicsConfig.json file, all virtual directory applications will report as nodes under this tier.
