A. Cimmino - P. Paolucci - G. Polese / DCS meeting DQM tool for the DCS data What the RPC community needs: 1.Make online/offline DCS data analysis 2.Produce a set of standard histograms, plots and statistical results 3.How correlates DCS and XDAQ data 4.Make custom online/offline analysis What we have done for the MTCC ? We developed a working prototype CAT (Control Analysis Tool) We would like to understand if a similar system has been already foreseen by CMS and if not if other sub-detector are interested in.

A. Cimmino - P. Paolucci - G. Polese / DCS meeting RPC CAT for the MTCC 1.Make standard/custom Query to the online DB 2.Produce a root file with a rootpla per datapoint Chamber: current, voltage, status and temperature Electronics & trigger: none up to now 3.Data analysis tool: Data synchronization (different time stamps) History plot (standard for shifter and custom for expert) Histograms to correlates different datapoint Warning and Alarms (to be done) Analysis tools Online DBRoot files DB query histograms

A. Cimmino - P. Paolucci - G. Polese / DCS meeting RPC CAT for the future CAT for chambers, electronics and trigger able to: Produce a set of standard histograms, plots, results and warning/alarms automatically for people in shift. Friendly user interface for more complicated analysis Data file available for experts What do we need to do that: 1.Standard/custom DB Query 2.Intermediate data format (root files) to prevent to many DB accesses 3.Analysis tools (data synch. and hardware-chamber mapping) 4.GUI for shifter. Experts can use root

A. Cimmino - P. Paolucci - G. Polese / DCS meeting Conclusions Napoli group is interested in the development of DCS analysis system for the RPC We have 2 people (phd and student) + Giovanni and myself Our exercise for the MTCC is working and is producing results (A. Cimmino) Can we use DQM or integrate it in the DQM ? There are other possibilities ? What about the other subsystems ?
