perfSONAR Toolkit on AlmaLinux 9

Overview

perfSONAR is the widely deployed open source toolkit for measuring and troubleshooting network performance, developed by ESnet, Internet2, GEANT and Indiana University. It runs active measurements between hosts, one way latency and packet loss with owamp and twamp, throughput with iperf3, round trip time and path traces, and coordinates them through pScheduler so tests are scheduled, de conflicted and run with the right tool. Results flow into a local OpenSearch measurement archive and are presented on Grafana dashboards, while a lookup service registration advertises the host so it can be found and tested against by the wider perfSONAR mesh. Research, education and enterprise network teams use it to find where along a path performance degrades, to prove a network is clean end to end, and to keep a long term record of how links behave.

Common uses

• Running scheduled latency, loss and throughput tests between network hosts
• Troubleshooting where along a path network performance degrades
• Archiving long term network measurements and viewing them on dashboards
