This component helps companies to transition their traditional products to a SaaS model. It does so by providing a usage-based pricing in a minimally invasive way, so that it can be added even to a monolithic architecture. While this is no substitute for a cloud-native architecture, it accelerates the lift-and-shift phase and enables one of the core SaaS attributes (usage based metering) out of the box. This is the technical prototype of a solution which I proposed in my Master's Thesis.
This is an analysis component which analyses the data provided by the proxy component via Mosquitto. It applies the rules from the rules.yara to the received data stream to determine which functionalities were used in the proxied application in order to bill the usage.
Yara doesn't compile under Windows... This program should be run under Linux
Set up a Mosquitto instance. I recommend using their docker image since it saves you the annoying setup.
Change the IP address to your Mosquitto instance in app.js.
$ npm install
$ node app.js
