Also reported on new dashboards in monit-grafana.cern.ch at https://monit-grafana.cern.ch/dashboard/db/lhcopn?orgId=14 (requires CERN SSO login) and perfSONAR infrastructure dashboard in Kibana
Update on Analytics
Ilija reported on work to find changes in packet-loss, throughput, etc. See paper https://arxiv.org/pdf/1508.01280.pdf
Trying this method on CERN-BNL link analysis. Machine-learning also being tried on perfSONAR data to find anomalies in
our data. (Someone working on Titan...need details)
Saul mentioned that MGHPP is down for maintenance and this was an opportunity to go to 100G. When site is back up it will be
using 100G. Shawn asked about using that path for LHCONE; Saul: yes, should be used.
Andy: minor update to pScheduler in the next few days (intermittent lock-up fix). IPv6 may be having some issues.
Marian: Question about Docker support for the full toolkit? Andy: being discussed if this will be done at next week's
face-to-face in Ann Arbor.
Lots of Q&A and account setup for meshconfig.
