OSG Investigations Team

GOC Transition is going to dominate the Investigations Team's time over the next couple of weeks. I want to give general status of the transitions we are participating in. So, I will give a couple of states:

  1. Have not started
  2. In development - Could be provisioning hardware, adapting software, installing software…
  3. Ready for testing - In a state where it can be tested by the consumers
  4. Deployed
Service Status
OIM In Development
OASIS Deployed
CVMFS Deployed
Software Repo Deployed
OSG Display Deployed
StashCache Redirector Deployed
OSG Collector Ready for testing


  • OASIS: Testing -> Deployed: Transitioned on 5/3
  • CVMFS: Testing -> Deployed: Transitioned on 5/3
  • OSG Collector needs discussion. CE's do not transition to the new collector without a restart.
