DQM tool for the DCS data

Control Analysis Tool (CAT) by

Cimmino, Lomidze, Paolucci, Polese

To1. Make custom DCS data analysis2. Produce a set of standard histograms3. Make online/offline expert analysis

RPC CAT for the MTCC

1. Make standard/custom Query to the online DB2. Produce a rootpla for the datapoints 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)

Integration in the RPC DQM

• After having discussed (24 january) with: E. Meschi, J: Varela and F. Gegle RPC needs to study how to:– Have in the DQM a way to retrieve “DCS and XDAQ

data” (online DB) in order to analyze and correlate them.

– Integrate in the DQM modules able to retrieve data from the online DB and produce some (few) standard plots.

– Produce a larger set of plots for the RPC experts.– Develop an analysis tool for the RPC expert (based

on ROOT with a WEB interface ?? How to access the DB data ??).
