Abstract	Resistive Plate Chambers have been used in the CMS experiment to build up a dedicated muon detector system which covers the whole geometric acceptance up to a pseudorapidity of 1.6 with a total of 480 chambers in the barrel and 432 in the endcaps. In order to guarantee the quality of the data collected and to monitor online the detector performance, a set of common tools has been developed in CMS and they are in particular heavily used in the RPC system: the Web Based Monitoring tools and the Data Quality Monitor system. The first ones are a set of templates available on the web which allow the user to check the hardware performance during data taking with distributions and plots of all the parameters. The Data Quality Monitoring service is composed by a set of algorithms which can work both during data taking and offline, running on stored data, to check the quality of reconstructed physical variables. Both these monitoring systems will be described here with a particular emphasys on their structure, functionalities and performance.
