DQM tool for the DCS data

What the RPC community needs:1. Make online/offline DCS data analysis2. Produce a set of standard histograms, plots and

statistical results3. How correlates DCS and XDAQ data4. Make custom online/offline analysisWhat 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.

RPC CAT for the MTCC

1. Make standard/custom Query to the online DB2. Produce a root file with a rootpla per datapoint

Chamber: current, voltage, status and temperatureElectronics & 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 datapointWarning and Alarms (to be done)

Histograms

<current> distribution of the 23 barrel chambers for a 4 days period with magnet ON and with stable conditions (offset subtracted)

<I> = 2.5 A

RMS = 0.5 A

Good to monitor “nervous”or unstable chambers

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

Conclusions

Napoli group is interested in the development of DCS analysis system for the RPCWe 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 ?
