An application is a collection of tiers. Each tier in an application is a collection of VMs and physical IPs based on the user-defined filter criteria. The applications allow you to create a group of tiers and visualize traffic or flows between the tiers of the same application and between applications.

You can create or add an application into vRealize Network Insight in three ways:
Application page provides complete visibility of a single application in vRealize Network Insight. This enables you to troubleshoot problems and also view the analytics.
