Development and testing of web GUI application for the LHCb VELO data quality monitoring system

Abstract

A great interest of IT engineers at CERN is to simplify the access to the Data Quality Monitoring(DQM) applications that usually lay behind several layers of security firewalls. In order to makeit simple and thus help to save time for the scientist who rely on this data, additional applicationfor the Web had to be developed and tested. The goal of this thesis work was to developsuch a Web DQM application for CERN. First, a Web Graphical User Interface (GUI) wasdeveloped. In parallel, an Apache server was installed and configured for testing. Moreover,software program called ROOTJS that processes and displays CERN data files on the Webwas presented. Through this thesis project, new functionalities were developed to meet therequirements. Furthermore, the ROOTJS program was merged with the Web GUI applicationand series of tests were performed to showcase the capabilities of the application which wasdeveloped through this thesis work.
