What perfSONAR is
perfSONAR is a free, open-source toolkit for measuring network performance across paths and helping engineering teams locate problems as they arise. It provides a common way to schedule measurements, store results in uniform formats, retrieve data at scale, and create visualizations. Operators can coordinate tests across multiple nodes using a shared JSON mesh configuration; results can stay on each node or go to a central dashboard server. A standard node runs throughput or latency tests on one network interface, although simultaneous testing on that interface may affect accuracy. Documentation covers Docker and Ansible deployment, a central archive with Grafana, and client and esmond APIs for accessing raw data. The software runs on a local server controlled by the operator, so users maintain the nodes and test configuration. It is licensed under Apache License, Version 2.0 and distributed without warranty. The project identifies science facilities, campuses, laboratories, network providers, exchange points, virtual organizations, researchers, and software and service developers among its intended users.
Who it suits
perfSONAR suits network operators and researchers who need coordinated measurements across network paths. It is also aimed at science facilities, campuses, laboratories, providers, exchange points, and developers able to maintain local infrastructure.
What it does well
- Free and open source under Apache License 2.0
- Coordinates tests across multiple nodes
- Stores results locally or on a central dashboard
- Provides APIs for raw data access
- Supports throughput and latency tests
What to know first
- Requires operator-managed local server infrastructure
- Users must maintain nodes and test configuration
- Concurrent tests on one interface may affect accuracy
- Distributed without warranty
Limits
The free toolkit requires user-managed infrastructure: operators must maintain the nodes and test configuration. Simultaneous throughput or latency tests on a single network interface may affect accuracy.

Getting started
- Visit the perfSONAR website and review its deployment documentation.
- Prepare an operator-controlled local server for installation.
- Use the Docker or Ansible deployment guidance if it fits your setup.
- Configure nodes and their shared JSON mesh for coordinated tests.
- Choose whether results stay on each node or go to a central dashboard server.
Verdict
perfSONAR provides coordinated network measurement and data access for operators managing their own deployment. It is free to use, but maintaining nodes and test configuration is part of running it.
Questions
How much does perfSONAR cost?
The listed plan is free. The toolkit is open source.
Is perfSONAR open source?
Yes. Its components and tools are licensed under Apache License, Version 2.0 and distributed without warranty.
