The web system described here provides functionalities to monitor the Detector Control System (DCS) acquired data. The DCS is responsible for overseeing the coherent and safe operation of the ATLAS experiment hardware. In the context of the Hadronic Tile Calorimeter Detector, it controls the power supplies of the readout electronics acquiring voltages, currents, temperatures and coolant pressure measurements. The physics data taking requires the stable operation of the power sources. The DCS Web System retrieves data automatically and processes it extracting the statistics for given periods of time. The mean and standard deviation outcomes are stored as XML files and are compared to preset thresholds. Further, a graphical representation of the TileCal barrels indicates the state of the supply system of each detector drawer. Colors are designated for each kind of state. This way problems are easier to find and the collaboration members can focus on them. The user can pick a module to see detailed information. It is possible to check the statistics and generate charts of the parameters over the time. The DCS Web System also gives information about the power supplies latest status. The barrel colors green whenever the system is on. Otherwise it is colored red. Furthermore, it is possible to perform customized analyses. It provides search interfaces where the user can set the module, parameters, and the time period of interest. Moreover the system produces the output of the retrieved data as charts, XML files, CSV and ROOT files according to the user's choice.
