  1. Web.Based.MonitoringStatus LHC@FNAL Meeting William Badgett, Steve Murray Fermilab Zongru Wan Kansas State University

  2. WebBasedMonitor, goals • Integrate information from across all CMS • Environmental, Trigger, DAQ, Luminosity, etc. • Extend “CMS Page 1” to provide more information to the CMS collaboration • Ability to “drill down” to get more details • Links to sub-detector pages already in development • Tools for remote ShiftCrew • Also useful for remote experts • Plotting “Value versus Time” in CMS database • Ability to plot anything vs. anything • Light-weight web interface

  3. Structure, directed servlets • Additional “Expert Tier” • Underlying infrastructure for more general pages • General database browser • For people who know a little SQL and would like to create new web pages – need to know where data are • Basic low level servlets • Tools for creating new pages, use Java inheritance to make it easy • Not intended for ShiftCrew direct use • DatabaseBrowser, SlowControlBrowser, RootBrowser • β versions already in place

  4. WebBasedMonitor, front-page http://cmsdaq.cern.ch/cmsmon/

  5. DatabaseBrowser, example

  6. DatabaseBrowser, example Automatic conversion from database table data to root TTree

  7. DatabaseBrowser, root conversion

  8. GenericBrowsing • Disparate set of database tables • Barely controlled chaos • No standard history model • Sub-detector specific tables • Need meta-data tables to describe them • Have settled on schema • Implementing user interfaces • General case of “Value versus Time” servlets can be extended to many data source • DAQ, Trigger, Lumi, Conditions, etc.

  9. SlowControlBrowser Since cmsomds erased, no data in standard PVSS tables

  10. RunSummary pages • Top level point to inquire about runs • Form with popular selection criteria • By run or run range √ • Date and time range √ • Trigger√ and run configuration • LTC MTCC triggers only • Events collected √ • Luminosity accumulated • Subdetector status √ • Presence in readout √ Implemented http://cmsdaq.cern.ch/cmsmon/ click on “RunSummary”

  11. RunSummary query page LHC info to be implemented Easy click for last 24 hours Subdetectors Triggers

  12. RunSummary, multi-run query Multi-run query results Can also run in test-only mode with wget command line

  13. RunSummary, single run • Clickable measurements • Drill-down capability • Plot creation • Provides root TTree and histogram object in file • Resizeable on resubmit

  14. LHC Logging • Equivalent to AcNet logging • Contains many interesting CMS data • E.g. magnet temperature, current • Accessible from protected P5 network and our web browser • More abstract database schema (easier to browse) • Fold into current CMS browser

  15. Conclusion • Propose implementing standard meta-data tables to describe wealth of data in CMS database • Based on ECAL and WBM proposals • Have schema in hand; testing • Implementation in progress • RunSummary actively being used • & extended • Will hook into LHC logger • Can LHC@FNAL benefit? • Have a look! http://cmsdaq.cern.ch/cmsmon/
