    FEC start-up and diagnostics (Frank Locci BE/CO)

    • LUMENS (start-up):
      • LUMENS replacing 30 year old ‘transfer.ref’ as start-up script for diskless FE computers
      • Commands and services extracted from controls configuration database (CCDE)
      • Hardware configuration with device-drivers (in transfer.ref) split from software service configuration (lumensctl)
      • Lumens programs as commands (start once and die) and server (run forever)
      • lumensctl –h shows commands
      • lumensctl –s <myservice> shows status for one service
      • Hope to migrate to ‘lumens’ for 2021 start-up (BE-BI 10 out of ~500 FECs)
      • Users can migrate their own FECs CCDE manually or automatically (send email to Frank Locci)
      • LUMENS:  https://wikis.cern.ch/display/LUM/Users+corner
    • Diagnostics
      • Front-end diagnostics provided by COSMOS
      • ‘Diamon’ console remains supported as before
      • Some options are protected by RBAC
      • Many more process metrics available with COSMOS
      • Web based data available using ‘icinga’ containing information from CCDE, LanDB, and cosmos
      • Dash-board information available through ‘grafana’
      • COSMOS:  https://wikis.cern.ch/display/COS/Users+corner
