Given the high granularity of the CMS sub-detectors, several approaches and tools have been developed to monitor the detector performance closely. We describe here the History DQM, a tool allowing the detector performance monitoring over time.2010http://cds.cern.ch/record/129034410.1016/j.nima.2009.06.109http://cds.cern.ch/record/1290344oai:cds.cern.ch:1290344
