NetV!sor Sender

This is the sender application of the NetV!sor suite, composed of the website, the gatherer application, and the sender application. This suite was created as part of a 3 month-long IT apprenticeship class project, where the requirement was to design and program a website that had a front-end, used PHP in the back-end, and communicated with a SQL database (ICT 120 and 151 of the 2014 curriculum). Projects were made by groups of 4 students, and no subject or theme was imposed.

About NetV!sor

This suite was made to monitor network-connected IT devices in order to spot potential network problems and / or help IT support teams debugging and preemptively spot potential problems.

About NetV!sor UI

This application works as a Windows service. The service starts when a user logs in, and periodically polls the hardware components to send information about them to the gatherer that is supposed to receive them. The application was fully written in C#.

It relies on information coming from Windows' WMI. It compiles the gathered data, before packing it and sending it to a gatherer. The application is very lightweight when idling and when gathering the information too.

The communication between the sender and gatherer applications uses UDP port 5252. Data sent via this port is clear-text, as there was is no real confidential information being sent. The communication is detailed in the technical specification document "netvisor_document_technique.pdf", written in French, included with released versions.
