Tau L1 Commissioning and HLT DQM

Complete: 1


  • Contact persons: Mike Bachtis, Konstantinos Petridis


The Data Quality Monitoring for Tau HLT goal is to provide code for online/offline monitoring of Tau HLT performance in data coming from the detector. It is split into Online DQM which runs on a stream with rate ~ 1 Hz and Offline DQM. The Offline DQM is executed at the end of the run after prompt reconstruction. In online DQM a set of backup triggers is utilized to evaluate efficiencies and quality tests.For offline DQM, the plan is to compare to offline Objects (PFTaus,CaloTaus,Electrons, etc) to get a first look on the efficiency and the fake rate of the triggers

How to run the Online DQM code

Create a new area:

scramv1 p CMSSW CMSSW_2_1_0_pre6

cd CMSSW_2_1_0_pre6/src

Download the code:

cvs co -r V03-00-29 DQM/HLTEvF

Build it:

scramv1 b

Copy a config file that runs with the backup table:

cp ~bachtis/public/RunHLTDQM.cfg .

or get it from here RunHLTDQM.cfg

Run it:

cmsRun RunHLTDQM.cfg

The default config file redirects the output to a GUI installed on pcwiscms10.cern.ch To access the output enter in the browser: http://pcwiscms10:8030/dqm/online For access outside CERN you need the standard tunelling.

Note: If you plan to use the GUI to run and monitor long jobs it is better to change the DQMFolder name. The reason for this is that if a lot of jobs send histograms with the same name to the same folder the GUI might crash. To avoid this edit the config file DQM/HLTEvF/data/HLTMonTau.cfi and replace

DQMFolder      =    "HLT/HLTTAU" with

DQMFolder      =    "HLTYourname/HLTTAU"

Remember to do it for all Tau paths in the file ..

How to run the Offline DQM code

Create a new area:

scramv1 p CMSSW CMSSW_2_1_0_pre6

cd CMSSW_2_1_0_pre6/src

Download the code:

cvs co -r V03-02-02 DQMOffline/Trigger

Build it:

scramv1 b

Run on QQH:

cd DQMOffline/Trigger/test

cmsRun HLTTauOfflineDQMTest_cfg.py

regarding the GUI And monitoring of the plots while it runs ,

same things apply as the Online DQM
