1.6  Virtual Field Agent (VFA) 

The GE Virtual Field Agent

 

(VFA) is a Virtual Machine that uses the Ubuntu operating system. It contains Predix Machine to allow 

streaming data to the cloud or running applications locally. It also incorporates User Interfaces for configuring networks and time 
synchronization, getting Field Agent Product and Linux OS Updates, and checking status and running commands. While the VFA is 
essentially configured the same way as an MFA or VFA, there are different Application and Configuration templates provided for the 
VFA, because these templates are associated with a specific version of Predix Machine. Currently the Virtual Field Agent is normally 
distributed as one of the possible Virtual Machines on a Control Server. To learn more about Control Servers, please see 

GEH-6851 

Control Server – High Availability (HA) Maintenance Guide

 and 

GEH-6852 Control Server – Simplex Maintenance Guide.
