Online monitoring / Presenter  In place  Monitoring of the L0DU bank  Check that TCK is known  Emulator Now from the L0DU bank only Possible: from sub-detector banks, from L0 sub-processor banks  BCID monitoring FPGA2 vs. FPGA3 / FPGA2 vs. ODIN  TLK / de-multiplexing / Tell1 errors  Error status  Summary Report  To do  Rates with trending By elementary condition By group of trigger channels  Test various TCK on zero bias data and inform shift crew when it is time to change the L0 algorithm because the instantaneous luminosity is lower  Alarms Régis Lefèvre - L0 Workshop - June 9th CERN7
