Monolithic Applications - Getting Started with Learning

Prerequisites

vFunction requires a Server to be installed for the backend analysis and the UI. vFunction also requires the vFunction Agent (Dynamic Analysis) and Viper (Static Analysis) process.

Getting Started

While an application is running, vFunction collects the data required for analyzing the application. This process is called Learning and the resulting, analyzed data is called a Measurement.

In the vFunction Server UI:

  1. Select the relevant application in the top-left dropdown
  2. Choose the Learning tab in the top-center menu bar
