OSG Investigations Team

This week is mostly catching up with the changes made over the break.

  • XRootD monitoring collector: Large refactor
    • Also making changes for WLCG compatibility.
  • StashCache Origin configs generated from Topology.
  • Re-organize caches behind redirectors to split load with I2 caches. Nebraska and KC cache first. Need to register the redirector with the cache discovery methods.
  • Perfsonar mesh for the StashCache nodes, or at least nearby nodes.

Finishing XCache is the focus for the next few weeks.
