  • (Ongoing) Getting sites to transition to the new HTCondor collector

  • Discussions with Internet2 to place StashCache in connection points.



  • (Derek) AI: Will speak with admins about moving IPs out of Anvil so that we don't have central collector downtime
  • (Edgar) AI: gWMS factories would like to generate factory entries based off information in CRIC, which will populate some of its data off of the central collector. Edgar will provide a list of info that he believe may be auto-discoverable on the CE to be advertised back to the central collector
