Cimmino, M. Maggi, P. Noli, D. Lomidze,
P. Paolucci, G. Roselli, C. Carillo
Anna, David e Pierluigi
DQM meeting - 26 feb 08 2
Online General Plan I
Large set of histograms chamber by chamberCluster Size, Nr of Digis, Multiplicity, BX, Occupancy
Small set of Summary histograms 5+1 Cluster Size by wheel & barrel
60 Occupancy by sectors
5 2D Occupancy by wheel
Quality test: statistical analysis, alarms, results in output file (ready)
histo comparision, output read from GUI, file repository (on going)
General Web based DQM GUI (WBM today) display Histograms, alarms and Qtest output file
Anna, David e Pierluigi
DQM meeting - 26 feb 08 3
Online General Plan II
RPC RenderPluginscolored histograms/plots (ready for summary histos)
alarm and warning text on the histo\plot (March)
reference histograms\plots (April)
could be more !!
Store output root files and ascii files in the CMS repository (April)
Online documentation for people in shift (operation manual, instruction and examples) (twiki page to update and improve)

Offline DQM I
What we have nowCluster Size, Nr of Digis, BX, Occupancy
Chamber and Trigger Efficiency (G. Roselli)
Chamber Noise
What we are planning to do2D efficiency (Radiography) (Napoli)
trigger data and DB usage (May)
Run quality studies
We have to estimate/measure the numbers and the performance of the offline DQM (how many histo/plot, CPU time….)
DQM meeting - 26 feb 08 5
RPC DQM group
Offline DQM II
We need an accurate offline trigger studies (Giuseppe) and correlate the results with the detector results
We need to access non event-data from the condition database and used them for more accurate analysis and checks.
Offline calibration to send back to ORCON (online):Dead and noisy strips !!
Efficiency chamber by chamber ?
DQM summary results can be stored in the ORCOF
central GUI and/or TBrowser to see histos

RPC DQM Plan for next GR
RPC Online part is almost ready. Few technical problems will be fixed soon - David
3-D occupancy plots by sector are now ready (new) - David
WEB GUI based on WBM is now ready
First Qtest prototype is ready (output ascii file) (new) - Annawe would like to merge DQMMonitorDigi (where the histograms are produced) and Qtest module (where the analysis is done) in only one module.
will check monitoring elements after every 1.000\10.000 entries (we have to discuss this ), in any case it is configurable by config. file
it produces output ascii file, in the near future WEB GUI will read it.
A first prototype of the RPCRenderPlugins is now ready (decorate or to write text on histograms) - David
OFFLINE: working on the 3-D efficiency histograms (chamber radiography) and on Trigger/Chamber efficiency (Giuseppe) (new)

QTests status and plan (A. Cimmino)
Dead Strip test: performed on the occupancy plots made chamber by chamber. Output ascii file and histogram with dead strips.
Mismatches with already known dead strips are reported. (80% ready)
Occupancy Difference Test: it retrieves reference histograms for each chamber and compares bin by bin. Output will be ascii file and/or histograms
Multiplicity/Cluster size:
It checks the last set of histograms with the references and produce an output file/plots.
It checks if the multiplicity is compatible in an “a priori” defined range. It checks how much the multiplicity of each chamber deviates from the average calculated wheel by wheel.

Offline DQM questions1. Which are the offline DQM modules (existing or planned) to
be run? 2. What is the status of the code development and readiness
for deployment?• RPCMonitorDigi ( RPCEfficiencyFromTrack.cc, RPCMonitorDigi.cc
RPCMonitorEfficiency.cc) 90% ready• RPCMonitorClient (Qtest) 30% ready• RPCMonitorModule (to delete)
3. Which are thepackages that we need to include?
//DataFormatsDataFormats/RPCDigi/DataFormats/MuonDetId/DataFormats/RPCRecHitDataFormats/GeometrySurfaceDataFormats/GeometryVectorDataFormats/Common
//GeometryGeometry/RPCGeometry/Geometry/Records/Geometry/CommonDetUnit/
//FrameWorkFWCore/MessageLogger/ FWCore/Framework/FWCore/ParameterSet/FWCore/ServiceRegistry/
//DQMServicesDQMServices/CoreDQMServices/NodeROOTDQMServices/DaemonDQMServices/UIDQMServices/ComponentsDQMServices/WebComponentsDQMServices/ClientConfig
Offline DQM questions4. It would be great to have some quantitative estimates of
a) the number of histograms and binsSummary histos/bins: 69 / 6.320 Occupancy by Weel: 5 histo 480 bins Sector Occupancy: 60 histos 5.760 bins Cluster Size: 4 histos 80 bins
Histos by chambers: 11.164 / 1.010.250Barrel:
1D. ~ 4800 histos, 700800 bins(ClusterSize, Number of Clusters, Number of Digi, BX, Occupancy)2D. ~1920 histos, 76800 bins(ClusterSize vs Strips, BX vs Strips)barrel total ~6789 histograms & 860720 bins
Endcap :1D. ~ 3125 histos, 309450 bins(ClusterSize, Number of Clusters, Number of Digi, BX, Occupancy)2D. ~ 1250 histos, 120000 bins(ClusterSize vs Strips, BX vs Strips)
Efficiency by chambers: 10.000 / 960.000
Offline DQM questions
5. the memory and CPU consumption ?
we don’t have this estimation – working on
6. the number of events required for good statistics:
1 milion of muons for the efficiency by strip
10 K of muons for the cluster size, multiplicy, noise and occupancy (by chamber)
120 K muons for the summary plots (by wheel…)
RPC
RPC Detector Status
We are now working on the definition of a detector status by sector wheel barrelThe RPC DS will be based on the detector occupancy and/or on the trigger rate Right now we will use only the detector occupancy checking:
average occupancy per chamber shape of the occupancy histogram the number of dead strips (“new” and “old”)
In any case we need to check also the DCS will provide information about the HV, LV and Gas status (FSM and alarm)

Conclusions
Online RPC DQM is almost ready: new 2D histograms (occupancy)
still working on more summary plots
quality test on going (dead strip ready)
Offline RPC DQM contains also: detector efficiency (ready)
trigger efficiency (working on)
Almost 22 K histograms 2,2 milions of bin
