[en] Full text of publication follows: A solution for monitoring computers, networks and software at Tore Supra. The monitoring of the computer systems involved in the daily operation of a tokamak is a large and complex problem. At Tore Supra there are more than 800 devices interconnected that offer a versatile set of functions and services. It is obvious that the needs and the goals of the different players involved in the control and the management of the different systems are widely spread, depending on their expertise (one person cannot be skilled on everything) and their role (responsibilities, authorizations...). Nevertheless they join together on one simple, in its wording, demand: to be rapidly warned when an issue occurs and have access to the best solution to fix the problem. To answer to this legitimate request the IT group have studied various open-source solutions and finally chosen Zabbix for his flexibility, its ease of configuration via a Web interface, the wide range of operating systems supported, and the great number of triggering methods which ease the integration of specific home-made controls.
