New repo-update-cadist will be installed on repo-itb; Tim T needs access to that host to test scenario where there are no MD5 sums.

OSG Investigations Team

  • 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.

Done Last Week: - HTCondor-TCP stats packaging for the submit nodes (SchedDs) - Monitoring working set size of StashCache caches now at bottom of kibana dashboard. - StashCP udpates, now can be installed by pip
