Architectural Overview - VF Server running via Podman
High-Level Overview
The vFunction Server running via Podman includes the following:
- 11 Podman Containers running on a Linux VM
- Three Podman Volumes for MySQL, Monolithic Measurements and Distributed Measurements Storage
- One Podman Network for managing communication between the Podman Containers
- One external Port open (80, 443, other) to listen for browser requests from end users and analysis information from the application(s)

Traffic Legend
External over open Port
End Users to Server
End Users access the Server via a Browser. Standard REST APIs are used to retrieve and update organization, application and measurement information and structure.
Agents to Server
The Agents send standard REST APIs to stop and start Learning and to upload Application details to the vFunction Server for analysis.
Internal over vFunction Podman Network
Nginx to API Containers
The Nginx Container forwards APIs from the browser or from Agents to the relevant services over Ports 8001, 8003, 8004, 8005, 8006 and 8007.
API Containers to MySQL Container
The API Containers send request to store and process all processed information.
Organizations API Container to SQL Parser Container
The Organizations API Container sends request to the SQL Parser Container to parse queries retrieved from .NET agents.
Measurements API Container to Measurements Volume
The Measurements API Container sends requests to store and retrieve raw data to the Measurements Volume.
Distributed Measurements API Container to Distributed Measurements Volume
The Distributed Measurements API Container sends requests to store and retrieve raw data to the Distributed Measurements Volume.
Information gathered by vFunction from the Application
The vFunction Monolithic Agent gathers information about the Application and sends that information to the vFunction Server for analysis. That information contains statistical and structural data based on the Application’s behavior, including:
- Callstacks
- Field, method and class names
- External HTTP Connection data (IP Addresses, Hostnames)
- File names
- DB Query Metadata (Tables and Stored Procedures)
