Mission of the Muon DAQ Online Monitoring

Online Monitoring of Muon data is done within the framework of the LHCb Online Data Quality Monitoring, which is under active development. Please note that:
  • we can only monitor events triggered and saved to disk by the LHCb DAQ. Thus, the Online Monitoring has only access to the list of firing logical channels and to their fine time, as given by the Muon TELL1s. Monitoring at lower level is done by the appropriate tools within the PVSS panels and is decoupled from this framework;
Changed:
<
<
  • the monitoring information consists of a set of histograms that can give a prompt feedback on the Data quality; the information must be syntethic and not redundant since we want to save the histograms at regular intervals and there are obvious technical contraints on the data size;
>
>
  • the monitoring information consists of a set of histograms that can give a prompt feedback on the Data quality; the information must be synthetic and not redundant since we want to save the histograms at regular intervals and there are obvious technical constraints on the size;
 
  • detector monitoring should be standalone. In the future, the Monitoring Farm will run the reconstruction on a fraction of events (10-50 Hz) to monitor tracks, etc.;
  • monitoring histograms can be seen online using the Presenter application, that is (and must be) only an histogram viewer, NOT a debugging or analysis tool;
  • for future stable DAQ operation, the possibility is foreseen to have automatic histogram analysis, generating alarms for the main shifters in case of unexpected problems.
