drunc issues prioritisation

Pawel:

• Progress since last meeting
  • Zombie process issue found, seems to work but tracing
  • Force flag for terminate (working, need to finish zombie review before PR)
  • Started planning what we want to publish with OpMon, but first how the metrics will be published need to be decided
• Objectives to complete until next week
  • Run number microservice bug
  • Continue OpMon work

Pierre

• Progress
  • FSM batch mode and prefix are gone
  • Started to look into drunc/ERS
• This week
  • Continue drunc/ERS (likely need a bit of rewrite a bit of the python bindings)
  • drunc-unified-shell / PM splitteroo
• Items for discussion (we need a green light from overall DAQ for both, I suspect)
  • Session renaming, are we doing it? (see presentation)
  • Hard coded port number, are we removing them? (I'd advocate for yes, since it looks like we are stuck with SSHPM for a while). Here is a list of places that I think will need change
    • Connectivity service incoming traffic port and how to feed it to the daq_application correctly.
    • daq_application/controller control ports and how to make it available in the connectivity
• grpc endpoint for applications -- design for v5.2

Speakers: Alan Watson, Alessandro Thea (STFC Rutherford Appleton Laboratory), Giovanna Lehmann (CERN), Gordon Crone (University College London), Henry Wallace (Royal Holloway, University of London)

Pierre

• Duplicated/messed up json for config in run registry -- Pierre checked which json is primary
• Plans for offline DB transition to OKS -- follow up at Collab meeting

Eric

• Command line tool to sort database so GtHub diff is usable
• Can be done with python interface

Speaker: Marco Roda (University of Liverpool)

Marco:

  • I'm working now on the restoring of the monitoring for the rest of the readout dpdklibs, hermes, flxlibs, etc
    • Dedicated dashboards are also slowly being restored.

• Discussions happening on the drunc monitoring side
