Hi Team,

I am Preeti Bhat from Caltech, working on network R&D for USCMS, ensuring PS nodes remain operational across all seven USCMS sites.
I have encountered an issue with one of the sites and would appreciate your assistance in resolving it. The BW node perfsonar02.cmsaf.mit.edu, running the PS Toolkit on bare metal, is currently not executing any throughput tests. As a result, I do not see throughput results on the Grafana dashboard and on central dashboard.
However, when I run iperf3 tests manually, throughput appears to be fine. I have already verified the following:
  • All pscheduler services are running
  • Opensearch is available
  • The PSConfig file is added
  • IPv6 is enabled and available on the interface
  • MTU is set to 9000
  • The required port is open (firewall configuration attached)
Could you please provide your input on potential causes or next troubleshooting steps?
Many Thanks,
Preeti Bhat
Caltech
