Check Which Tags Are In A CMSSW Release

• look into /afs/cern.ch/cms/sw/slc5_compiler/cms/cmssw/CMSSW_X_Y_Z/src/PackageList.cmssw, e.g. /afs/cern.ch/cms/slc5_amd64_gcc462/cms/cmssw/CMSSW_6_0_0_pre2/src/PackageList.cmssw

OR

* from https://cmstags.cern.ch/tc/, select the release and the Show All Packages option and then click on the submit button

Check Which Global Tag Was Used To Process A Data File

edmProvDump rfio:rootfile | grep globaltag

Find The Most Up-To-Date JSON file

• on afs at /afs/cern.ch/cms/CAF/CMSCOMM/COMM_DQM/certification/Collisions11/7TeV/
• on the web here

Query The DBS From lxplus

dbs --search --query "find min(run),max(run),dataset where site=caf.cern.ch and dataset=*MuonDPG*"

How to check a trigger path description

Info taken from the following hypernews, https://hypernews.cern.ch/HyperNews/CMS/get/hlt/2640/1/1.html.

• For the HLT technical details at the DB browser is your best bet is http://j2eeps.cern.ch/cms-project-confdb-hltdev/browser/

When you open a menu there's a "Summary" tab at the upper right that if you click will try to display only the thresholds/cuts used in the last filter modules in the HLT paths.

• For Level 1, you can get the list of menus here, https://twiki.cern.ch/twiki/bin/view/CMS/GlobalTriggerAvailableMenus

and then follow the links to "HTML view of physics algorithms and scales"

How to check when a particular trigger path was prescaled

edmConfigFromDB --runNumber 136132 | hltDumpStream | grep '\<HLT_L1MuOpen\>' | head -n1

How To Resubmit a specific job on CRAB

• if the status of the jobs in question is "Killed", "Aborted" or "Done" and the "Exit_Code" is not 0, they can be resubmitted immediately with the same executable and the same settings by
  crab -resubmit job-id -continue crab_?_date_time where job-id can be a single crab job-id, a comma separated list of job-id's or a range of job-id's from the status check.

• To resubmit all "failed" jobs at once (ignoring jobs with "Done" or "Cleared" status)
  crab -resubmit -continue crab_?_date_time

• IMPORTANT: if the status is "Done" and the "Exit_Code" is not 0, the user has to retrieve the job output before he can resubmit the job

How To find Prescales

Instructions are at https://twiki.cern.ch/twiki/bin/viewauth/CMS/HowToFindPrescales
Access them in the HLT, https://twiki.cern.ch/twiki/bin/view/CMS/SWGuideHighLevelTrigger#Access_to_the_HLT_configuration

From a json file on a specific hlt path

• lumiCalc.py -r 147206 -hltpath HLT_Mu9 --nowarning overview
• lumiCalc.py -i Cert_132440-147116_7TeV_StreamExpress_Collisions10_JSON.txt -hltpath HLT_Mu9 -o myoutput.csv --nowarning lumibyls

Check Prescales Changes During a Run

• go to cmswbm page, https://cmswbm.web.cern.ch/
• select your run, e.g. for run 190949: https://cmswbm.web.cern.ch/cmswbm/cmsdb/servlet/RunSummary?RUN=190949&DB=cms_omds_lb
• click on PrescaleChanges and you will be redirected to https://cmswbm.web.cern.ch/cmswbm/cmsdb/servlet/PrescaleChanges?RUN=190949
• there you go!
