The results of structural and thermal monitoring of the Compact Muon Solenoid Experiment at CERN will be reported. The measurements are carried out by means of Fiber Bragg Grating sensors arrays installed on the CMS detector, from the inner to the outer parts. This fiber optic monitoring system represents the ideal solution to realize a reliable and accurate sensing system to be used 24/7 in the harsh environment at CMS. We will report data concerning temperature and strain measurements recorded during CMS operation throughout 2015.
