Offsite notes and action items[edit]

Data Data Data[edit]

  • Talk with Analytics - JR
  • Talk with CE/Bitergia - JR
  • Explore Bitergia - JR
  • Identify data sources we want to collect - RelEng (who know what systems)
  • Erik Bernhardson / Guillaume Lederrey
    • After we get our list of data sources talk to them


  • TODO: Tyler reasses scap swat in mw-config from Mukunda
  • Look into parsing scap messages for known patterns and pulling out the data
  • Look into enabling scap start/done
    • This should be trivial
  • Look into recording if mwdebug was used during the deploy (eg: 'scap stage')
  • H/Now will we get time for this?
  • Have Mukunda do a couple weeks of SWATs
    • Mukunda has a lot to say about this subject.... writeup incoming

TODO tl;dr: Tyler taskify the above and talk to Mukunda


  • Greg to talk with Deb about what to do next with talking to Victoria
    • Done
  • Greg to figure out how we can better market what we are accomplishing (eg "monthly showcase")
    • TODO
  • Get a k8s cluster from SRE for CI to deploy to.
    • Dan/Tyler discuss later today
      • potentially poke/get a commitment on a timeline soon
