Shift Organisation

A GEOC shift lasts for a full week from Monday to Sunday. Before starting at shift s/he shall check that
• has a proper CERN account
• has a Grid proxy and is registered to the LHCb VO in VOMS with lhcb_admin and lhcb_shifter roles
• is subscribed to necessary mailing lists (see the GridExpertOnCallLinks page)
• is in charge on updating this guide

See GridExpertOnCall2018 for the current stats per GEOC.

Changes 2018

Some recent minor changes when hosting a meeting for the shifter.

  • When cloning the ops meeting, be sure to clone all of the contents as these contain useful links to material being discussed
  • You will need to be able to project & share the meeting page so that people can see GGUS tickets, plots, etc
  • Taking ops minutes is as before but there is a template on indico


For shifters not familiar with the DIRAC interface (who don't use it daily but are familiar with it).

  • To get to the shift monitoring plots load this_url . This should log you into the dirac portal with the lhcb_shifter role and take you to the "Public State Manager".
  • Refresh this page if you don't see an expandable tree for Desktops/Applications
  • Find the Desktop called "Shifter_Overview" from mcnab
  • Click on the grey box in the load column
  • Click on the load icon from the popup

This should now load multiple tabs containing all of the monitoring plots of grid resources. You should regularly loop through these plots throughout the day whilst on shift every 15-30 min should suffice but more frequent is better.


The GEOC is the central point of info, operations and management for LHCb Distributed Computing Operations, in this role s/he is the first contact point for everything that concerns LHCb Distributed Computing Operations. The GEOC

• Manages and possibly solves all issues, otherwise relays problems to the next line of support
• May involve others: relay to “LHCb 3rd line support or ask shifters for help
• Receives info from Shifters, Sites, Production teams, LHCb/DIRAC developers
• Provides info to Sites, WLCG Services, LHCb Online
• Organizes, participates to LHCb/WLCG meetings
